Please let me know if any of that output was useful. Stratum disconnects seemto affect my USB AsicMiner Erupters.

Thanks these are very useful. In particular they've told me exactly where in the cgminer source it's failing so I can try and track it down:

Code:

Failed to recv sock in recv_line

Okay, email sent with a 1.5Mby attachment.

Running a second run with -P -D -T 2>log.txt

This seems to have less data, but seems still relevant for what you want. I'll send email #2 soon.

EDIT: corrected, was running 2>log.txt not 1>log.txt

Email with the second, 2.0 Mby attachment sent.

I'm running now -P -D -T >log.txt

There is A LOT of data, including shares.

yes I think I need to use something like 2>%1 log.txt hold on.

it outputs COM port device discovery information only, so far in the first 5 min or so. Will email you if I get anything more in the next hour or so.

Possibly windows logs things differently. When I run with that I immediatly get a low level list of everything going on, including all traffic sent to and from the pool. For example:

please could you lower your minimum withdraw, its far higher than other pools and takes an eternity using my single gpu, especially with the difficulty rising so rapidly.

The reason for not being too low is to prevent accumulation of dust amounts in both the pool wallet and the user wallet. This results in higher fees when those funds are spent. I'll add lowering it to the list of things to investigate though.

Just ran this

./cgminer -o ... -u ... -p ... -P -D 2>log.txt

on Win 7

it outputs COM port device discovery information only, so far in the first 5 min or so. Will email you if I get anything more in the next hour or so.

I'm using cgminer v. 3.3.1. The first 550 Accepted shares report only 2% HW errors, which is almost normal. However, I just saw "lost 2 shares to stratum disconnect" on pool 0. HW error did not occur in this instance.

Are you able to run it with the"-P -D" switches for "protocol dump" and "debug" respectively? You can pipe the output using "2>log.txt". So something like:

Code:

./cgminer -o ... -u ... -p ... -P -D 2>log.txt

If you can send the log to [email protected] or see anything relevant in there around the disconnect it would be useful.

Just restarted and am watching the screen. Will report if the situation changes.

What miner are you using? cgminer v3.2.1?

I was (as of a few minutes ago) still getting "stratum disconnect" messages as reported above on this page. At the same time, the ASICMINER USB Erupters report a few HW errors through cgminer. The rate of HW errors comes to about 10% which is way above the usual 1.5%.

Just restarted and am watching the screen. Will report if the situation changes.

What withdraw fee? There isn't one.

There was a pool restart just now as I rolled back to bitcoin 0.8.1 to see if the recent upgrade is the cause of the instabilities.

The amazing thing is that the pool server remembered those few shares that got lost during the crash.
That's why after the server recovered the hashrate went up for a moment despite my rig automatically switched to a different pool:

Share's are kept in a queue and if they fail to transmit to the database server they wait until the database becomes available again. When restarting the pool services this results in a bunch of shares in the queue getting submitted when the database server comes up again and it often shows up as an increase in hash rate like that.

Yes, the bitcoind crashed.

22:30: {"hashrate":540.609,"pps":0.00000000,"score":4312, ...

22:32: {"hashrate":533.885,"pps":0.00000000,"score":4318, ...

By the way, I wish the payout process from the "crashed" exchange.bitparking.com could run as smoothly as doublec's pool software ...

Looks like somebody gave 'er the 'ol reboot.

Yes, the bitcoind crashed. I'm having a few problems with the recent upgrade to bitcoind 0.8.2. I'm running under the debugger at the moment to try and see what's going on. Worst case I may need to rollback the last update.
