scheduler problems on AIX4.1



I'm having problems with the zmailer-2.99.26 scheduler (on AIX 4.1.4).
The scheduler hangs and keeps it's children pending forever. The
effect is that messages are not passed to the transport agents, mailq
hangs etc. Anyone got a clue?

Running the scheduler in verbose mode gives this:

.
.
.
pick_next_vertex(proc->tofd=7, thr=0x20019e20, jobs=1 ok=1)
 ... NONE, idle the process (of=0, f=1).
<96Mar15.141037+0100msz.3102-25304+1@alba.$orgdomain|alba.udac.uu.se>: unlink 
3102-22480 (mid=0x2001a7d4)   and ../queue/3102-22480/
delete_thread(0x20019e20:local/martin@alba.its.uu.se) (thg=0x20019cb8)
delete_thread(1b) thr->proc=0x0 pid=0
22650 fd=7 processed: #hungry
pick_next_vertex(proc->tofd=7, thr=0x0, jobs=0 ok=1)
 ... NONE, we are idle.
sig_chld() pid=13182, ok=1, stat=0x100
sig_chld() pid=24950, ok=1, stat=0x4b00


And thereafter nothing more, and no way to contact the scheduler without
restarting it.
