Hello
It's not interesting what is after GET, interesting is that PID number
is multiplexer.

Maybe your server is segfaulting when receives a vulnerability scan:
http://wiki.combatx.net/W00tw00t.at.ISC.SANS.DFind:)
I tried to reproduce this problem here, running DFind on a test machine,
without success.
Can you try to scan your server with DFind and see what happens?

Hello
I studied dump of processes of apache and discover this, always crash
multiplexer. From this results question, why processes of multiplexers lists in
apache status dump? After restart apache is no multiplexer in this list. I
think the problem occurs when multiplexer processes appears in list of server
status processes.
Sorry for my terrible english.
