Re: [ldm-users] noaaport issue in latest ldm version

Howdy! We seem to be having a problem with noaaport in the latest release of ldm 6.12.9. More specifically... when ldm is started, the system load goes sky high until noaaport eventually crashes. I have included a snippet of the ldmd.log file. Any clues? Thanks! Bruce 

Bruce Haynie,

I am able to reproduce your issue:

The LDM stops ingesting data, the CPUs go to 100%, and then blammo.
Anyone who is using or thinking of using 6.12.9 for ingesting data via satellite...don't. Something is wrong with it. For just being a relay or individual receive site not connected to a dish, it's fine. 
It's been running for a week with no problems. It's only affecting those
who have dishes. I am running CentOS 5.

I have a trouble ticket filed with UNIDATA on this as of 2 PM CT.
