Hi all, We're currently attempting to diagnose a problem on an LDM node which we believe has a major backlog of data to download. When we attempt to start LDM, it quickly takes over all available memory and the load skyrockets, until the server chokes and dies. Server has 8 cores and 32 GB memory, and 8 GB swap. As of right now, the load is over 600 and nearly all memory is in use. We are not sure exactly what the cause of this issue is in LDM... only that as soon as we start LDM, the load goes through the roof. This issue occurred once before, which we solved with a memory upgrade 8GB->32 GB. Now it's happening again with more memory. :P LDM version is 6.8.1. Can anyone suggest a way to instruct LDM to rate-limit itself, or otherwise set a resource limit so it doesn't murder the server it's on?
