[Twisted-web] Silently dying server processes started with twistd

being in the early production stage of two http servers implemented with
twisted/nevow and making heavy use of athena I observe the following:
Either server dies silently after some time ranging from 10 mins to
several days with the logs being inconclusive and stopping at random points.
Process image size is stable at around 120 MByte, number of concurrent
users is around 150, CPU load per core is around 20%.
All my testing does not reveal a single problem, everything runs fine
until I let 'normal' users hit the server.
The underlying OS (OpenBSD) is of no help, not a trace of the process in
question can be found, it looks like they vanish into thin air.
I am stumped about processes vanishing, no core, no log entries, no nothing.
Does somebody out there have a clue on how to debug such a problem.
