Monitor & restart JSS. It runs from launchd every 60 seconds. [code]#!/bin/bash
#
# Monitor JSS:9006 and restart if down. #

JSSURL="http://jss.company.com:9006"
restartlog="/Users/syadmin/Logs/JSS_restarted.log"

# Program runs once per monitoring interval
rc=/usr/bin/curl -s -I --max-time 2 $JSSURL | grep HTTP/1.1 | awk '{print $2}'

This is a real shot in the dark, but have you looked at your unmanaged clients recently? This may be a unique issue to our deployment, but I ran across about 800 clients that were previously managed and decided to flip themselves to unmanaged (this was probably a result of my JSS upgrade) I was maxing 500 database connections and crashing my JSS in about 20 minutes or so. I searched for unmanaged clients and retyped the management account name and password for the whole list and within 15 minutes or so my average database connections went from 500 to about 20 and my clients fell back into management. I am running Mac 10.8.5 with server app on a xserve, MySQL 5.5, and JSS 9.21. I called JAMF support to see if bad management account info will not allow the client to drop the database connection and am waiting for a response.
