Hello,
Answering my own mail ;)

Still, something locks up in the system, when I increase the number

The frequency of these messages increases with 70 threads. And with
200 threads the system locks up totally -- almost no access from web.
[I can still access the system and kill the process :) ]
Clearly, there is some limit in the system. It is not memory, cpu or
bandwidth. If the number of threads is also not limited, it must be
something else. What might it be?
Eventually, I found out that the limiting factor here is named, not
capable of handling more request and causing Apache to lock up.
But now I am trapped here. Is there anybody who can help?
In /var/log/messages:
named[63198]: socket: too many open file descriptors
I have googled this, but no help. Recompiled bind, adding
-DFD_SETSIZE=2048 to CFLAGS. No help.
sockstat |grep -c named
does not big numbers. With 60 Grubng/Pyhton threads this number is
around 20, rises over 100 with 100 threads, but this is still much lower
than 2048...
Any ideas?
Regards,
O.K.
