Can you make a thread for your problem? Include things like kind of computer, which version of BOINC, which OS and what projects you are part of.

How do we make sure that our Team "EVGA DC Captains" account is not removed and deleted. The Account manages all of our BOINC Projects.


I gave the account and the host for the account 3 credits so that it won't get picked up by query as the total credit is now greater than zero.

It looks like you can download. Why you can't process is a different issue. Microsoft's choice to have Windows 10 override the video drivers has caused lots of problems. I would check and see if you can download an updated driver from nVidia and see if that solves it.

Then again, at the moment it appears the server is in 'fragile' mode...

Since you already have an account here, you don't need a invite code. Just attach the project on your computer.

OK -- so we know that at the moment, the database server is fragile or unstable.

Perhaps a sense of whether or not the light at the end of the tunnel is an oncoming train?

Slicker, I suspect the daily server crashes resulting in extended outages have got to quite a bit more frustrating for you than we mere clients.

Do you have some thoughts on the problem source and potential solutions?

I also wonder the same thing. Jon we all need maybe an update to the server issue and also if this project will continue with this type of issue. Please remember we all wish success for the project but having computers sitting doing nothing is why most if not all run these projects. Many thanks for all your efforts Jon!

Regards,

Message 23538 - Posted: 8 Dec 2016, 23:52:50 UTC

The MySQL daemon crashes during backups. There are no errors in the syslog or the mysql logs. The only thing logged is that it is shutting down. In order to limit the down time, I plan to change the backup time so that it occurs in the early morning rather than at midnight. That way it will be down for less time.

The only info I've found suggests that a corrupted innodb table could cause the crash. Yet, when I re-run the backup script it always completes without errors which implies that isn't the case since a corrupted Innodb table would crash every time the corrupted data was accesses. I realize MySQL is free and that's why it was chosen, but I really wish BOINC was database independant (e.g. compatible with SQL Server or Oracle, either of which I consider to be much more stable.)

What size is your swap file? Also are all CRON JOBS finishing properly? Also have you tried to move the SQL DB on to a different drive and test on the new HD?

Look forward to answers and maybe a solution.

The swap size is 4x the actual memory size and the memory size is never 100%.

http://dba.stackexchange.com/questions/27328/how-large-should-be-mysql-innodb-buffer-pool-size

Just looking around and well came upon this. 4X on SWAP is really huge on the server side also let alone on SQL side. I have a location using MySQL on a Linux box with 8 lanes in a Grocery getting hit 8 hours hard a day and it just runs and runs.

Maybe too much is masking the real issue, maybe lowering it could point to other issues.

innodb buffer pool isn't exactly the same thing as the swap file. I read and tuned every MySQL setting including the buffer pool long long ago.

Okay that is good sounds like the application calling into the MySQL is maybe your issue. Is there an application or is this all scripts running things. Wondering are you making TEMP query dumps to memory or HD space. If you make memory dumps are you clearing it with code or just overwriting it? Sorry for all the questions but that's programming.

I have spoken to a few others on this and well they think you may have a bad stick of RAM. They think when it is called upon to store data it is bad and could be the item hanging. I would get some type of ram tester software and do a aggressive test(pattern) against the total ram or take out a pair at a time and see if that helps you find out if it is hardware.
