Hi Brad,
You are running out of file descriptors, type this:
kes# sysctl -a | grep files
kern.maxfiles: 20000
kern.maxfilesperproc: 18000
kern.openfiles: 5230
kes# limit -h
cputime unlimited
filesize unlimited
datasize 1048576 kbytes
stacksize 262144 kbytes
coredumpsize unlimited
memoryuse unlimited
descriptors 18000
memorylocked unlimited
maxproc 4115
You probably increased the number of tables in my.cnf and did not
allocate enough descriptors for the process.
use sysctl to increase the number of available descriptors.
Ken
