ob4 crash potential multi server clash

[Steven Hartland]

Strange stack trace
(gdb) info stack
#0  0x0851922d in qsort ()
#1  0x084bec3e in tstp ()
#2  0x0851171a in recvfrom ()
#3  <signal handler called>
(gdb)

Also note that all servers on the box died with a few seconds
of each other. Some sort of conflict? Perhaps all trying to use
the same temporary folder / file at the same time as where
all started together so a map change issue?
