Steps to reproduce:

1. Build Zabbix Agent for Solaris 10
2. Run agent unconfigured/configured - doesn't seem to make a difference whether its actually doing any real work or not.
3. Run ipcs -s | grep zabbix periodically to watch the semaphore count grow until it maxes out
4. Stop the agent
5. Run ipcs -s | grep zabbix to check the count and notice only 1 was removed after exiting
6. Run ipcrm to clean up semaphores

Result:
See attached zabbix agent log file, alongside a log of output from a loop that's counting the number of Zabbix semaphores:

for i in `seq 1 1000000`; do date >> /oanda/var/tmp/semaphore.log; ipcs -s | grep zabbix | wc -l >> /oanda/var/tmp/semaphore.log; sleep 1; done

Expected:
Semaphores were stable under 4.0.5, so I'm unclear when this changed exactly.
