It flooded my dmesg and messages with these messages (which is normal): Jan 29 18:13:20 tormentor kernel: maxproc limit exceeded by uid 1001, please see tuning(7) and login.conf(5). Jan 29 18:13:25 tormentor kernel: kern.ipc.maxpipekva exceeded; see tuning(7) but i've also noticed several mangled messages in the log, like these : Jan 29 18:08:25 tormentor kernel: kernmaxpr.ipc.maxpipekocva excee limidet exd;ce sedeeed t buninyg( u7)id 1001, please see tuni ng(7) and login.conf(5). Jan 29 18:08:28 tormentor kernel: Probably this is some sort of race condition, either in the kernel output or syslogd? --niki
