Hi Jan,

we had 65k for pid_max, which made
kernel.threads-max = 1030520.
or
kernel.threads-max = 256832
(looks like it depends on the number of cpus?)

currently we've

root@ceph1-store209:~# sysctl -a | grep -e thread -e pid
kernel.cad_pid = 1
kernel.core_uses_pid = 0
kernel.ns_last_pid = 60298
kernel.pid_max = 65535
kernel.threads-max = 256832
vm.nr_pdflush_threads = 0
root@ceph1-store209:~# ps axH |wc -l
17548

we'll see how it behaves once puppet has come by and adjusted it.

Thx!

 Benedikt
