Harry, > I am having a problem running LDM 6.6.4 on a 64 bit Linux box (x64_64 > architecture). The server runs okay for awhile, but then one of the > processes becomes CPU bound. It seems to be stuck in the loop in > rl_fext_add in pq.c that starts at line 1760. Have you seen this before? I haven't seen that before. The code is going through a skiplist that's ordered by product-size. Offhand, I'd say that it's impossible for that loop to be indefinite unless the product-queue has been corrupted (assuming, of course, that the code is correct). Try stopping the LDM and executing the command "pqcheck -vl-". Does it indicate that the queue is OK?
