Description:
Mysql server crashes often under even moderate load. Once a day approximately. Sometimes there is "mysqld got signal 6", sometimes there is "mysqld got signal 11". It always crashes with small number of thread connected. The server is HP ProLiant 2*AMD 64 Opteron 275 (Dual Core), 4 Gb RAM, 10 GB swap. Error log detailes follow:

Assertion failed: "Pure virtual method called." == "Aborted", file my_new.cc, line 51
mysqld got signal 6;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help diagnose
the problem, but since we have already crashed, something is definitely wrong
and this may fail.

key_buffer_size=268435456
read_buffer_size=2093056
max_used_connections=1032
max_connections=1700
threads_connected=24
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 7218530 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Thank you for a problem report. Please, try to repeat with a newer version, 5.0.27. In case of similar crash, please, send your my.cnf file content (I suspect that out-of-memory issue is quite possible).

We have installed mysql 5.0.32 from sources. I will notify you if the problem persists.

We have totally replaced the previous configuration with the default one (mysq_huge.cnf with innodb enabled). Server ran smoothly 4 days.
Yesterday we noticed that our application needs group_concat_max_len=16k (larger buffer for gorup CONCAT). We executed SET GLOBAL group_concat_max_len=16384. Today server crashed two times:

mysqld got signal 11;
This could be because you hit a bug. It is also possible that this binary

Today it crashed once more. The only change in configuration was setting the default value for group_concat_max_len. We removed group_concat_max_len from the configuration, but it didn't help.

I suspect that it crashes some time after heavy load.

Well, is there anything we can do to clearify the situation? Turn on any debugging switches, run any debugging utilities? Frequent crashes just ruin all our work...
[13 Jan 2007 18:51] Dmitry Kochin
One more crash today. But now we have core dump.
It can be downloaded (172 Mb, archived) from http://haddan.ru/download/core/core_db2.haddan.2007-01-13.rar
I hope it will help.

Hi Dmitry,

That sounds very similar to our problem. With the exception that in the first few crashes for you MySQL actually tried to backtrace. This is very frustrating. We've duplicated this problem on multiple Solaris 10 platforms (S10 Update 3 [AMD64 & SPARC], as well as Solaris Express Community Release Build 54 [AMD64]). I think we will finally get MySQL 5.1.14 to core dump properly, just waiting for it to do so. It has stayed up since we turned core-dump on and used coreadm to put the corefile  in /tmp/ (verified with gcore). 

Have you had any luck with an analysis of the coredump by MySQL?

(Cross-posting from http://bugs.mysql.com/bug.php?id=25460).
[18 Jan 2007 18:19] Jason Williams
Dmitri,

What version of Solaris are you running? Also, are you running UFS or ZFS as the filesystem?
[18 Jan 2007 22:07] Jason Williams
Hi Dmitri,

We noted a rapid connect/disconnect sequence during our 127 errors. This was noted in the general_log. Have you noted anything similar during your crashes?

Best Regards,
Jason

Solaris 10 6/06 s10x_u2wos_09a X86 on Dual Core AMD Opteron 64.
mysql bin's are on UFS, dtatabase is on ZFS.

We didn't notice rapid connects-disconnects before the crash. We have 300-400 queries per second and cannot turn on general query log.

We didn't analyze core dump because we just didn't know how to accomplish that.

Hi Dmitri,

This may help: http://dev.mysql.com/doc/refman/5.0/en/using-gdb-on-mysqld.html

We finally got a core last night. Be interested to compare your backtrace from GDB to ours.
[19 Jan 2007 14:21] Jason Williams
BTW, you may want to upgrade to Update 3 or newer. ZFS's block cache by default will suck down all of your RAM minus 1GB. With Update 3 or newer there's a less than elegant way of getting ZFS to cap that. With Solaris Express Community Release Build 54 or newer there's a tunable you can set to cap the ZFS block cache to a maximum size.

http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6505658

Also, if you have a ton of small files on your ZFS filesystem you could suck down up to 3*block_cache (ARC) in RAM. But that's really rare...if you just have MySQL DB files it hasn't been a problem for us. Just needed to adjust the max ARC (block_cache) size.

Hope this helps.

Jason and Dmitri,

Can you, please, send your backtraces to this bug report?
[22 Jan 2007 18:00] Jason Williams
Hi Valeriy,

I've posted the GDB backtrace to case 25460. It should be downloadable here I think: http://bugs.mysql.com/file.php?id=5431
[23 Jan 2007 8:34] Valeriy Kravchuk
Jason,

Do you think this bug report is related to bug #25460? Maybe, they are duplicates (about the same problem)?

I will check backtrace, surely...
[23 Jan 2007 18:46] Jason Williams
Hi Valeriy,

I'm not entirely sure if its the same bug. Dmitry cross-posted on our bug (25460) that this might be the same. As far as I can tell, the main similarity is the crash without backtrace. I'm curious if Dmitry is using a MySQL built binary.
[23 Jan 2007 18:58] Dmitry Kochin
We used mysql built binary 5.0.24a. It crashed often. We built mysql 5.0.32 from sources. Nothing changed, crashes happened the same way.

We are going to apply recent patches to Solaris. If it continues to crash we will build community mysql 5.0.33 with debug info.

Unfortunately we failed to generate GDB backtrace from the dump file. Can anyone here do it? The core dump is here: http://haddan.ru/download/core/core_db2.haddan.2007-01-13.rar
[23 Jan 2007 19:00] Jason Williams
Hi Dimitry,

Is the mysqld that crashed in the RAR as well? If not, where can we get at it?
[23 Jan 2007 19:12] Dmitry Kochin
No they are separate.

The core dump:

Yes, it is readable by dbx.

Dmitry, you said in the comment to bug #25460 you have other 4 dumps. Please, upload some: I want to check if crash always happens in one place. Thank you.

Sveta, have you managed to find the cause of the crash?

By the way, after Solaris update mysql performed faster and didn't crash for 4 days, but crashed again today.

Dmitry,

thank you for the uploaded core files. Your problem seems to be different from bug #25460.

If you can build and run 5.0.33 with debug info, please build and send core file of it.

Please try current version 5.0.51a and if the problem still exists try to compile debug binaries (--with-debug=full) to we can see more information in cores.
