Merry X-mas everyone!

Just wanted to let Rob know I woke up this morning to find my client stalled again with the latest version.

My cgminer shows that it had a rejected block, three new blocks passed after that and then that is where the client stalled at, so it seems to be the same situation that someone else was having earlier.

Web site upgraded:
 
http://www.gridcoin.us
 
Upgraded the block explorer to a new version of IIS.

Running 1.1.4.5 now. "Up to date" at 36842.

Edit: It didn't last. Got windows message Gridcoin-Qt has stopped working. Display showed "Up to date" at 36786(!).

Apparently we're not going to move past 36775, so I had to create a new version again:
  (This change worked in testnet; but obviously not going to work in prod).


 I changed the checkpoint to block 36810, and now we're going to try something better; discard the orphan if it fails the boinc hash.

Please download the 1.1.4.5 Prod MSI or Upgrade.

Thanks,
Rob H.

Version 5.8.3 (1.1.4.4) is available for download:
You can type "upgrade" from the RPC for this version.
 
The following changes have been made:
1. We disabled the blockchain snapshot feature in hopes after block 36775 and a 51% majority upgrade the root sync issue will be fixed, and to alleviate the cgminer restart problem.
2. Fixed the communication with the cgminer API.
3. Added a CGMiner monitor checkbox, that will automatically restart the API if your mh/s drops to zero; it is checked once every 5 minutes.
4. Added a 25 second delay to initialize the miners so that the client can start quicker and smoother.
5. Fixed the close guiminer/close cgminer bug (IE we start the API once and only once, and monitor it once every 5 minutes).

PS - TribalBob-- The snapshot feature was the culprit for the Cgminer close problem; please try this version.  Also, the sluggishness bug "should" be fixed in this version; please update us.

We still have to wait for block 36775 to pass with 50% upgrading before we know for sure; lets cross our fingers.

Also, my external cgminer is still crashing every 10 - 15 minutes even with "restartwallet=0" set.

Reproduced:  You found it!  We are storing a mined stale block that does not validate the boinchash as an orphan; its propogating and getting stuck at the end of the blocks table.  The only workaround is to re-sync.  I think this is the whole problem.  I'll fix this and test now; will release a fix as soon as it is tested!

Thanks for finding this!

Please forgive my bumping this part of my earlier post. I'm still trying to make sense of the BOINC projects panel. I've found old tutorials, but they only show how to set up new BOINC project accounts (assuming that users are new to BOINC) and they refer only to project names hard-coded in the panel.

My situation differs somewhat. I've been using BOINC through BAM since 2009 and my projects were in place before I set up Gridcoin. I've found advice to add projects to the project panel but I've not found a way to do it. Also, the information I've seen advises replacing project IDs at each individual BOINC project home page with a Gridcoin payout addy. This seems onerous and would negate the advantage of dealing with BOINC projects through BAM. Does it really have to be like that or am I finding outdated advice?

In summary:

Is it necessary to use the project panel at all to mine Gridcoin and get credit for BOINC activity?

If so, is there an up-to-date tutorial link, especially one that shows how to enter pre-existing BOINC project data?

Is it really a requirement to enter a Gridcoin payout ID on each relevant BOINC project's home page? If so, explanation might make it a more palatable requirement.

Thanks - I'm getting there - I'm in the top 1% of BOINC users so I'd really like to help the Gridcoin effort.
