I am running version 3.23.51-log (built with -O3) on FreeBSD-5.0-CURRENT on Alpha. InnoDB is on raw disk. After a week of uptime it restarted by itself and the message below was logged.
Looks like it was trying to allocate 4GB+0x1E bytes. Machine has 2GB of physical memory + 1GB swap. Database is small: around 1MB. And mysql memory usage was reasonable (150M). 100M was allocated for key_buffer. Could it be related to 64-bits pointer size on this architecture? Any ideas what could have caused the problem?
