Hmm OK, so it's effectively 12 devices.
That's a lot of GPU devices

The RSS number is (obviously) what shows if you are using up more RAM and running out of it.
I guess what's needed now is to find out what is happening when that changes ... and does it jump up in steps, or is a gradual rise?

Edit: oh I just noticed another thing ... you have 2 pools and the main is GPUMax - does it swap pools a lot?

They are all 5970's (dual gpu) so those temps are okay. I was actually using Phoenix until I just recently started with cgminer and had those clocks stable on phoenix for several weeks.  Not sure how often BAMT requests via API.  I have BAMT running on 2 rigs with 3 7970's each with same version of cgminer and do not see the issue on there.  I'll try running stock for awhile and see what happens.

OK 53 isn't a big number so it's not what I was considering may be the cause.

The other two numbers there are not big yet either
SZ=185303 RSS=388892
if you have a sizeable number of devices on your rig (your options suggest 6 GPU devices? Are any of them dual?)

My rig has only 4 devices and it reads:
SZ=151618 RSS=127032
(and yes I use the code also from my GIT except I don't enable Bitforce being compiled in, I only add Icarus at the moment)

However, in my case it doesn't run rampant later on.

Definitely getting nowhere with this so far looking at the system process info.

How often does BAMT request status info from the API? And what API requests does it use? (I don't know exactly)
I guess if there was some accidental fast loop missing a delay accessing the API over and over again that might cause issues?
My monitoring in my current setup is a set of 3 API requests every 10 seconds, but in my previous configuration (same code and hardware a week ago) I also added on top of that another 1 API request every second - but that didn't cause extra RAM usage.

I guess I'll defer to the expert (ckolivas)
Going idle can be for two reasons, as you suggested if GPUMax isn't providing you with any work, but of course the normal reason is as ckolivas said, if your setting are too high.

Are those temp settings and clock settings in any way high for your GPU's?
(The numbers themselves don't seem high for many cards - but I guess that depends on what the cards are - and if they are old and no longer stable if OC'd)
Do you ever get any status change on any of the GPU's? (i.e. not Alive)

Oddly enough I am working on a notification Java app that uses the API that might help monitor this problem (that comment above about 3 API every 10 seconds - summary,devs,pools) if it is temp/clock related
(The code already done would be enough)
But I've been expending a lot of effort on threading the data handling part of it (and probably making it too complex) to ensure that blocking code is in threads unrelated to time sensitive code (and then there's the issue of RAM usage in Java that I need to resolve next ...)
So I seem to be talking way longer than I expected to get even a beta out

Here's the information you requested:

Hey Con. Will you release a version with kanos work that supports mining with Icarus and BFL (windows7, 2.3.1f) ? There is a 7.5 BTC bounty for that. Would be nice

Some questions regarding this
1) When you run "./cgminer --help" what does the 2nd line "Built with ..." say?

2) run "ps -eL | grep cgminer | grep -v grep | wc" and it will say how many threads there are

3) run "ps -eLF | grep cgminer | grep -v grep | tail -1" will show you the command running cgminer so you can be sure it matches exactly what you said

Then you're onto something. It is dangerous to try and delete the ram used by the old threads because that just leads to a crash, so I specifically made the threads' ram not get cleaned up - so it is expected that ram usage will go up. However, you're doing something horribly wrong if your GPUs are going idle all the time. That's supposed to ONLY happen if your GPUs wedge because you're overclocking them too much and the GPU stops responding. I highly recommend reviewing your temperatures and clock speeds.

Thank you very much!

I mentioned guiminer becuase I used it in the past to do solo mining.
It sets my username/pass for solo mining and also launches btc client in server mode.

Sure you can.  Why wouldn't you be able to do that?

As long as you have your bitcoind/Bitcoin client started in server mode and the block chain up to date.

I don't know anything about GUIMiner and have no idea what that would have to do with anything.
Sam

I didn't know that command existed.  Nice.

A BIOS flash will take care of that clock/voltage issue nicely.     (Assuming it's a dedicated rig, of course)

Hi  

I have a doubt...
Sorry if this is already asked but 235 pages are too long to read  

Can I set "Solo Mode" mining in CGminer as follows?


Username and pass for solo mode mining are previously set with guiminer.

Thanks in advance  

No and it's a shame because the good info is just spread out all over the place on these forums 

2.3.1f OK That's from my git that was added to BAMT after 2.3.1 was released
That was to add API support for FPGA's ... 29-Feb ... yep.

That problem description might suggest a possible problem ... not related to my git change ...
If no one else has said or done anything when I wake up I'll look at making a quick test binary for you then
- but it's 3am and I'm tired and likely to make mistakes now

The web server part is only for rig mining stats (BAMT).  It's cgminer that keeps growing in memory size.  I've been watching and I think every-time a thread is idle for 60 seconds and is restarted, it increases overall RAM usage (like the previous thread isn't getting removed from RAM).  I use gpumax, which can have high idle times occasionally....  cgminer starts at 174 meg of RAM for me and currently its using 800 meg, so I think adding another stick of RAM would help, but only by delaying the time it takes for the system to run out of RAM.  If I restart cgminer, then its back to normal mem usage and slowly increases again.

I've been reviewing the command switches and am not sure which one increases the time a thread can be idle before cgminer restarts it... can someone assist me with what switch does that?  I would like to set the thread idle limit to 120 or 180 seconds to see if that reduces my thread restarts (and therefore RAM usage).  I'm on cgminer v 2.3.1f.

Your machines run out of memory.

You mentioned those are not dedicated mining rigs running web servers as well.
Just add a $12 memory module. As a stop gap, create a swap file.
Quest complete, you gain 200 experience points.

I'm very confused by the overall driver version thing. Is there a post (on this forum or somewhere else) that clarifies driver versions, OpenCL versions, which versions to use, how to change them and so on? I'm using Windows 7.

Neither am I. But I can recommend dropping intensity since 10 does not help anything less than a 7970 and consumes more CPU and makes hashrate more unstable. 7-9 depending on card is optimal.  There is a value, beyond which, the hashrate does not go up. 8 for most cards, 9 for 69x0s and 11 for 79x0s (only with export GPU_USE_SYNC_OBJECTS=1 on linux, otherwise again 9).

I just noticed that link was wrong - it points to miner.h not miner.php
Oh well I'm sure anyone (other than Xiangfu who is also using it other than me) who did want it, they would have worked that out.
The correct link was:
https://github.com/kanoi/cgminer/blob/master/miner.php

Thanks... I don't use the submit-stale option...  When i start it uses about 174 meg of mem, then a couple hours later, its using closer to 400 meg

this is my start script

I'm not sure whats going on...

898.1 is the sdk that's distributed from driver version 12.2 onwards, but it depends on which OS/combo etc. Having a different opencl.dll I'm not sure what it means.
