Assuming you haven't deleted any programs or links that xcd_run uses, I've seen this problem when ldmfail runs and there are poor network connections to both feed sites. Somehow this affects the way xcd_run works. The solution is to shut down and restart your LDM (after making sure all LDM processes have died). Another option is to comment out ldmfail from your crontab and see if the problem goes away (but then you won't have automatic failover). >Any clues? Tom will have to look at this when he gets back because another site reported a similar problem. I'll talk to Robb about this also. If you are not running ldmfail, let me know as this would indicate that there is a different problem. Also, check to see if the broken pipes happen right after ldmfail is run (usually 0, 20, and 40 mins past the hour). Don Murray
