Semi OT: MySQL memory probs...

[Randy Melder]

Group,

Got a problem with a client's MySQL server. It's an OS X tiger server w/2 intel
cpu, 8gb RAM, 80GB hdd (70% used). It's got 128mb free memory. When
MySQL gets a large query, it gets memory allocation errors. Binary and
error logging are turned on.

After a lot of googling... it appears that the MySQL binary for OS X
is 32bit and has an allocation limit of 2gb. I dunno if that is our
probe here.

Details:
mysql  Ver 14.14 Distrib 5.1.22-rc, for apple-darwin8.5.1 (i686) using
readline 5.0
