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:
Tasks: 208 total, 7 running, 201 sleeping, 0 stopped, 0 zombie
Cpu(s): 62.5%us, 0.0%sy, 0.0%ni, 37.4%id, 0.0%wa, 0.0%hi, 0.0%si,
0.0%st
Mem: 6096936k total, 2804116k used, 3292820k free, 214356k buffers
Swap: 8388600k total, 0k used, 8388600k free, 1827916k cached
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

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.
