Hi list,

Same thing here, mysql 3.23.51 works well during about 2 hours then
suddently load average grow up to 200 and more ...
Load average is less than 4 with 3.23.49.

We're using binary tar.gz non max versions from Mysql.com

OS : Linux Red hat 7.2
kernel : 2.4.10
1 Go RAM
2 * Intel 1 Ghz

During the load pic i've run a ps -eo pid,tt,user,fname,tmout,f,wchan and
that's an extract of the output :

So we come back to 3.23.49 wich have a glibc bug and memory eating bug but
we can't upgrade to 3.23.51 :(

Thanks again.
David
