I've had the same problem on an Intel P-III 800 w 256M RAM running FreeBSD 4.1-RELEASE
with
both the distribution from the ports tree and the source dist. from mysql.com.
I tried to solve the problem with analysing all the database traffic, but mysql were
taking all free CPU
that were availble on the same database traffic (same database) that were running fine
on a debian linux
machine (Pentium 166, 192M RAM) ... So something weird is happening on some FreeBSD
machines.
But I also have two machines that are _dedicated_ mysql servers of the same
configuration, but other
hardware brand (motherboard, scsi controllers, disks) that runs perfect on the same
FreeBSD release!
The machine with the problem were also running Apache/PHP ..
(How )is MySQL using sharedmemory segments ? I know that Oracle takes up loads of them
and may
bring problem for apache that also needs some seg's.. ?
