hi! I am hoping someone has experienced this before or knows how we can resolve this. I am running into an innodb assertion error (see below) and cannot reproduce it. It has happened 3-4 times, MySQL crashes and sometimes recovers and other times it is unable to recover (MySQL repeatedly crashes)
121013 13:36:01 InnoDB: Assertion failure in thread 1258400064 in file /export/home/pb2/build/sb_0-2859905-1295560203.65/mysqlcom-pro-5.5.9/storage/innobase/row/row0sel.c line 4465 InnoDB: Failing assertion: trx->isolation_level == TRX_ISO_READ_UNCOMMITTED InnoDB: We intentionally generate a memory trap. InnoDB: Submit a detailed bug report to http://bugs.mysql.com. 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://dev.mysql.com/doc/refman/5.5/en/forcing-innodb-recovery.html InnoDB: about forcing recovery. 121013 13:36:01 - 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=16777216 read_buffer_size=2097152 max_used_connections=158 max_threads=5000 thread_count=84 connection_count=84 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1321033337 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. We found open MySQL bugs that look similar http://bugs.mysql.com/bug.php?id=61088)? Has anyone seen this or have any ideas on how we can work around this?
