[LDM #MKY-400850]: Continuing issue with no TIRC headers getting into secondary LDM box



Gilbert,

Now we're getting somewhere.

The "Unable to receive" message are due to an upstream LDM process on Bird01 
that's sending notifications to a notifyme(1) process on Ldm01 not getting a 
response to a notification from the notifyme(1) process within 35 seconds 
(which is a very long time). Consequently, there appears to be some impediment 
preventing or delaying responses from a notifyme(1) on Ldm01 from reaching 
Bird01. This could be due to a miss-configured firewall (e.g., iptables), or a 
network monitor throttling the connection, or a bad Internet connection, etc.

It could also be due to killing the notifyme(1) process on Ldm01. I suggest 
running a notifyme(1) process on Ldm01 while watching the LDM log file on 
Bird01 to see if the corresponding upstream LDM exits before the notifyme(1) is 
terminated.
