Antwort: Re: Perf-Problem - Not more than 255 Childs?

I'm sorry, this is not the answer because the system doesn't swap heavily 
and the memory is ok too.

But I think there are some Kernel limits to 255 Procesess...

###
less /usr/src/linux/include/linux/limits.h
[...]
#define OPEN_MAX         256    /* # open files a process may have */
[...]
###

We will try to fix this in a few days...

Thanks
