Nagios and passive checks

[pshemko]

Hi,

I have a Nagios configuration with over a 1000 checks (services). All the
status information are sent directly to Nagios through it's command file.
There are up to 2000 results a minute, up to 20 processes sends data to
Nagios. 
The problem is that within 10 minutes even up 3000 messages are lost -
processes that write to the command file (pipe) simply can't write and time
out. If message can't be sent for 10 minutes to Nagios it's discarded. On
the other hand sometimes for over an hour there are no problems at all. 
It's not load-related issue as the load never gets higher then 1 - 1.5 (box
is dual Xeon 2.8Gz, 2GB RAM). Nagios doesn't execute any active checks. 
The writing processes are written in Perl and use the following syntax to
send data:

open NAGIOSPIPE, ">>$commandFile";
syswrite NAGIOSPIPE, $messageList;
close NAGIOSPIPE;

Does anyone have a clue why the processes timeout so often?

Regards
Pshemko
