Hello, Our NWSTG NOAAPORT receiver decided to quit yesterday afternoon, so we've become dependent upon IDD to fill the void until the receiver is fixed. I always have the IDD running all the time for possible contingencies and whenever I check the LDM program and the data everything seems to be fine. However, Murphy's Law seems to be ringing true and I've detected new problems that I had not encountered before. The first problem is that for some reason, I will have duplicate LDM processes running--one set owned by ldm (as it should be) and the other set of one or more processes owned by root (which should not be the case). I can't find any place where root could have started the LDM. When I do get LDM running again, I then have to clean up the problem of files created Secondly, over the past 24 hours, I have also had LDM die (no processes). I use ldmfail, but that hasn't always seemed to correct the problem. The final problem is that the normally reliable "ldmadmin stop" command does not always seem to be stopping ldm processes, such as, pqing, pqexpire, pqinstats, etc.(all owned by ldm), although it was stopping the rpc.ldmd processes. Before I noticed this, I had restarted and stopped the ldm a few times for some pqact.conf changes and then detected several pqing, pqexpire, pqinstats, entries. These behaviors seem extremely strange and I can't seem recall ever seeing the last two--has anyone else noticed anything similar. Jim -- James P.
