Dccm troubles

Hello, I recently started using dccm to filter our email and have found
that dccm seems to "die" fairly frequently. I have 4 dccm servers 3 are
BSD/OS 4.1 and 1 4.3.1. All of them seem to stop running. The 4.3.1 seems
to do it less. I have gotten 2 cores. All machines are running sendmail
8.12.9

One from the 4.3.1 running dccm 1.2.2

This GDB was configured as "i386-unknown-bsdi4.3"...
Core was generated by `dccm'.
Program terminated with signal 6, Aborted.

and one from 4.1 running dccm 1.2.3

This GDB was configured as "i386-unknown-bsdi4.1"...
Core was generated by `dccm'.
Program terminated with signal 11, Segmentation fault.

#10 0xa0034de2 in _thread_kern_start ()

But most of the time it seems to just stop running with no core. The last
messages in the logs look like this

Sep  4 18:03:10 trout dccm[22855]: 1.2.2 rejected messages to 649 targets
and discarded messages to 0 targets among 1306 total since 09/04/03

Thanks,
