I'd personally start by adding time markers to your submit_check_result
script around important sections --

#!/bin/bash
LOGFILE=3D/usr/local/nagios/var/submit.log; export LOGFILE

echo -n `date` . " " >> $LOGFILE 2>&1
echo "Entering OCSP command " >> $LOGFILE 2>&1

{command line processing code}

echo -n `date` . " " >> $LOGFILE 2>&1
echo "Calling send_nsca " >> $LOGFILE 2>&1

{send_nsca command}

echo -n `date` . " " >> $LOGFILE 2>&1
echo "NSCA exited with exit code: $? " >> $LOGFILE 2>&1

echo -n `date` . " " >> $LOGFILE 2>&1
echo "Exiting submit_check_result" >> $LOGFILE 2>&1


That'll give you an idea if the delay comes from calling the ocsp
command in general orsend_nsca itself.

I've been on the lists for 4 years and I don't recall it. That's a lot
of time to forget things though and not many installations are of that
size. At any rate, it's not common. What Ethan knows of it only he can
say.
