Gilbert,
With your experience as a LDM maintainer you should be able to start
diagnosing these type of problems. The previous line states that :
child 9389 terminated by signal 11
Then the main ldmd process rpc.ldmd[9386] dies. I would suspect that
process 9389 would be the culprit, that's pqact. Did you make any
changes? If not there could be an error in the pqact with products coming
from UIUC. There might be different products in the UIUC stream verses
the U-W stream. Could test this by commenting out the exec pqact entry in
the ldmd.conf line. I let you solve the rest.
