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?
Yuri.
