Zabbix agent item failed

[suprstar]

I keep getting: "Zabbix agent item [custom.mdstat] on host [myhost.mydomain.com] failed: another network error, wait for 15 seconds" in my server log, I dont know why. On the host I have:

UserParameter=custom.mdstat,sudo /opt/megaraid/check_lsi_raid.py | grep -c "All arrays OK"

in /usr/local/etc/zabbix_agentd.conf, and it appears to be working:

root@myhost:/usr/local/etc# zabbix_agentd -t custom.mdstat
custom.mdstat                                 [t|1]

The '1' is the return value I expect and want to see triggered if it comes back 0. I have a similar setup with linux software raids that is working perfectly. I have this line in the /etc/sudoers:

zabbix ALL=(ALL) NOPASSWD:/opt/megaraid/check_lsi_raid.py

which appears to be effective when I run with user zabbix on a command line:

root@myhost:/usr/local/etc# su - zabbix -c "sudo /opt/megaraid/check_lsi_raid.py"
No directory, logging in with HOME=/
RAID OK: All arrays OK [1 array checked on 1 controller]

What am I missing here??

The answer ended up being the 3 second timeout. The raid check takes about 6 seconds to complete, upping the timeout value on both server and agent made it ran perfectly.
