That being said we have only one scheduled task scoped to all of our computers and randomized by 45 minutes with just under 5k clients. <BR>
We set that one up on our roll out and I haven’t messed with it since. Just seems weird that it would still hang due to that even though most of the clients are off and not reporting in anyway. <BR>
<BR>
I’ll try increasing the packet size again, not sure that I can change the everyhour bit though since I don’t want to set it to report only one day a week or something. And there are not any options in scheduled tasks to do like every 3 hours and randomize by 2 hours or something. <BR>
<BR>
Thanks for the tips,<BR>

<B>Subject: </B>[Casper] Java freezing up JSS<BR>
<BR>
Hey has anyone else encountered an issue where every once in a while java seems to eat up a bunch of available memory and then the JSS will stop responding? If I go in and kill the java process it just restarts and everything is good to go, but it’s kind of obnoxious, and very random. It just happened here, and no one was actively using Casper. In fact we’re on spring break so most of the computers that are in our policies and such are shut off too. I had 0 connections to the casper share, and java was eating up just over 2GB of Real Memory and I believe over 5GB of virtual.<BR>
<BR>
Thanks<BR>
