Colin, what version of MySQL you are running and on what OS?
The assertion means there is an attempt to reference a pointer which does not point to the buffer pool. It might be memory corruption or table corruption. If you have updated to new disk drives in Linux, best to check if there are newer drivers. Please send me the complete error log so that I can resolve the stack traces if possible. Best regards, Heikki Innobase Oy ................... We just brought a database back up after bringing it down for a hardware upgrade (added hard drives) and after we brought it back up it started crashing a lot. The queries that crash it vary. I realize it might be simple case of database corruption (the data files are now on a different physical drive) but I thought I'd post it here in case the logged messages ring any bells. Relevant info: InnoDB: Assertion failure in thread 24601 in file ../include/buf0buf.ic line 263 InnoDB: We intentionally generate a memory trap. InnoDB: Send a detailed bug report to [EMAIL PROTECTED] mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked agaist 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=268431360 record_buffer=1044480 sort_buffer=1048568 max_used_connections=19 max_connections=200 threads_connected=20 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 670938 K bytes of memory Hope that's ok, if not, decrease some variables in the equation Any ideas? - Colin --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
