Ryan,

A quick look at the ldmd.log file you attached shows repeated assertion
failures for the LDM applications pqbinstats, rtstats, and pqact.
One example (for the inquiry tracking system) is:

Jan 09 21:13:52 kiloaoloa pqact[11253]: assertion "tvp->tv_sec >= 
TS_ZERO.tv_sec && tvp->tv_usec >= TS_ZERO.tv_usec && tvp->tv_sec <= 
TS_ENDT.tv_sec && tvp->tv_usec <= TS_ENDT.tv_usec" failed: file "pq.c", line 
4935

Since all of these programs read the LDM queue, it is safe to assume
that you queue got damaged somehow and needs to be remade:

ldmadmin stop
ldmadmin delqueue
ldmadmin mkqueue
ldmadmin start

Also, it wouldn't hurt to verify that the LDM configurations are still
in place in the following files:

/etc/rpc
/etc/services
/etc/syslog.conf

I don't add this because I think that they are causing your problem,
but, rather, because these files could get changed during an OS upgrade.
