Hi Brian!

I'd be interested in an answer to this too.
I haven't done in-depth analysis like you, yet, but it seems like we're
affected by the same problem occasionally.
Can anybody comment on this? 

Regards,
Florian Kirchmeir

	This is a multipart message in MIME format.

	I have a problem with Passive Checks timing out.

	From nagios.log, the services appear to have result commands
still coming 
	into the system. The difference in timestamps from the last
message to the 
	timeout message is way too low for the service to timeout. I
thought that 
	the commands were taking too long to get through the IPC and get

	registered, but that isn't the case (or at least when I send
through a 
	message with an invalid host and service the warning message
only takes a 
	couple of seconds to appear in the log).
	By looking at the source code, the first thing I found out is
that the 
	timestamp in the nagios.log
	[1087236197] EXTERNAL COMMAND: 
	PROCESS_SERVICE_CHECK_RESULT;<hostname>;<service
name>;0;<message> does not correspond to the time used for the freshness
check. I prepended 
	the timestamp for the result to the message to see those times
and print 
	the timestamp at the check. I also added print statement of the
timestamps 
	in the write_svc_msg and read_svc_msg to track their progress
through the 
	system.
	I've got one instance where a message with a much earlier
timestamp 
	appears after several others. There's the section of nagios.log
