Please, send the results of: show variables like 'innodb_locks%'; This looks like a duplicate of bug #27294.

I change the OS from FreeBSD to Linux. Please close this bug, I will open a new bug happening on Linux.
Description: I am sure running with enough memory (4G real memory, datasize 2621440 kB). The OS is FreeBSD 6.2-RELEASE, and mysql-5.0.45 binary distribution. It crashed in the morning, with very low loading. 070722 7:53:57 - 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 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=4190208 max_used_connections=111 max_connections=130 threads_connected=35 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 1326582 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. Assertion failed: ("Pure virtual method called." == "Aborted"), function __cxa_pure_virtual, file my_new.cc, line 50. Assertion failed: ("Pure virtual method called." == "Aborted"), function __cxa_pure_virtual, file my_new.cc, line 50. Fatal signal 6 while backtracing 070722 07:53:57 mysqld restarted How to repeat: not sure.. It happened almost once a day.
