Alan,

I can't read the log file but here's a couple things to check:

- make sure your pqact entries have matching parens for all the
references, ie \1 to first set of parens.  We found out that if  your
entry doesn't have a set of parens for a reference, then it causes pqact
to crash and the ldm crashes also. This is sometimes hard to find because
it only happens for the one entry and a product for that entry might only
arrive every couple of days.  

- Check you disk space, since the LDM queue is a sparse file, it doesn't
allocate the whole space requested on creation.  It may take a couple of
days to obtain the actual requested space. Use du verses ls on the ldm.pq
for the actual disk allocation.
