I mistakenly said earlier that I was not using a -t option, but you're 
right and "ps -wwax" shows that I am using one. It's what you'd 
expect from DCCM_REJECT_AT and DCCM_LOG_AT in dcc_conf, though:
-t CMN,10,10.

I think I've misunderstood the meaning of DCCM_ARGS in dcc_conf: I 
thought those were the only arguments passed to dccm. Since my 
DCCM_ARGS doesn't have a -t option, I mistakenly thought it was 
running without one (and using DCCM_LOG_AT and DCCM_REJECT_AT without 
being passed those values on its command line). Sorry for that

I will try this. My understanding is that this gives a preference to 
that server, adjusted by -2 seconds to whatever its preference would 
be anyway, so that it will likely be consulted first.

Thanks very much for looking into it. I'll try to make it happen again 
if I can.
