Bug Description
CentOS 6.3, fully patched as of 2/27/2013
Percona rhel6 rpm's for 5.5.29-rel29.4.401
server is a slave, DB Size = 2.8TB, 95% innodb, 5% myisam.
This server crashes roughly every 2-5 days with the following stack trace from the error log:
130226 14:12:11 InnoDB: Assertion failure in thread 140352895031040 in file buf0buf.c line 2608
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://
InnoDB: about forcing recovery.
20:12:11 UTC - 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.
Please help us make Percona Server better by reporting any
bugs at http://
key_buffer_
read_buffer_
max_used_
max_threads=3000
thread_count=95
connection_count=95
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Thank you for your bug report. The crash looks identical to bug 1086700, thus I'm going to close this one as its duplicate. Please track that bug and add any comments there.
