I think I even tried requests locally from the server and they still failed. I can't be sure about that last statement, it was a long day.

What are all of these closed connections from? e.g. conn=71007, 
conn=71003, etc.?  Are they from the load balancer?

I'm not really sure how to proceed to diagnose this from the directory 
server because events like these usually indicate something is happening 
at the TCP/IP layer.

I would be really interested to see if you continued to have problems if 
you shut off the load balancer completely and just contacted the 
directory server via the loopback interface.

It's similar to the B4 - it means there was a problem with the 
connection to the client.

>> Started to play with FDS 1.1 for some dogfood testing. After running for 10-15 minutes, the server stopped responding to network requests and went silent. The process was running, the error log was updating with the ldbm event loop, but no socket requests were fulfilled. Checking the access log, I saw this:
