Hi List, We have a mysql-Server with 8G of Ram. But mysql doesn't use this ram. But we get following error:
May 14 22:56:11 sql mysqld[5875]: 070514 22:56:10 [ERROR] /usr/sbin/mysqld: Got
error 12 from storage engine
May 14 22:56:11 sql mysqld[5875]: 070514 22:56:10 [ERROR] /usr/sbin/mysqld:
Sort aborted
I have set the sort_buffer_size to 1G but even this doesn't help.
Any hints ? Should we try a 64Bit-OS ?
Regards
Christoph
Kernel is a 2.6.18-3-686-bigmem from debian-etch.
