Nope - this is related.

Sorry, i meant: The daemon is freezing in the mclpl-status and cause
of that i have to reboot. This happens every some days or sometimes
serveral times a day. I called this 'the machine is crashing once a
day', but it is still the mclpl-problem.

I have several outputs from lsof, ps, top from this problem:

i just grepped the httpd-lines out of a top- or ps-output during that
situation. Donno if this helps anything.
I will try pavels idea 
'netstat -mssv with a kernel built with "options MBUFTRACE"' 
as next step.
