[LDM #UHC-293816]: EOF on socket 1 - what does this mean?



Mike,

> ldmping -i 0 localhost

> rpc_stat
> Apr 20 21:00:07 INFO: Resolving localhost to 127.0.0.1 took 0.000191 seconds
> Apr 20 21:00:07 INFO: RESPONDING   0.000737  388   localhost

The ldmping(1) program only tries to connect to the LDM server.  If it 
succeeds, then it immediately closes the connection, so the LDM server never 
has a chance to determine what the other process wanted.

Consequently, you may safely ignore these informational messages.

I added those messages some time ago.  They probably didn't show up until you 
updated the LDM.
