[LDM #UZO-863208]: Nooaport/ldm issues


> We have been running nooaport ingest software version 1.3.0 and ldm version
> 6.7.0 here at the FAA. We had a dedicated noaaport machine running
> ldm providing data to a downstream ldm server. After a recent
> power outage the nooaport machine failed to come up due to a hardware
> failure (a PCI bridge problem). Repair necessitated replacing the
> mother board. After some issues with the IP configs we were able to

The LDM log file on the NOAAPORT system has the following:

> Oct 19 02:53:45 ldmsat[4351] NOTE: Starting Up(6.7.0/6): 
> 20101019180636.712 TS_ENDT {{ANY,  ".*"}}, 
> SIG=b7a9d04da9cde5e3ee4783fe1094d2b0, Primary 
> Oct 19 02:53:45 ldmsat[4351] NOTE: topo: 
> {{ANY, (.*)}} 
> Oct 19 02:56:45 ldmsat[4351] ERROR: Couldn't flush 
> connection; nullproc_6() failure to RPC: Unable to receive; 
> errno = Connection reset by peer 
> Oct 19 02:56:45 ldmsat rpc.ldmd[4339] NOTE: child 4351 exited with status 6 

This indicates that the LDM on the NOAAPORT system tried to send data to host but was unable to because that downstream LDM no longer existed.

Are there any corresponding entries in the LDM log file on host 
that would indicate what the problem was?
