[Casper] Java freezing up JSS - Which version of JSS

[Dorey, Dustin]

Well that was my thought at first too, except when it just happened
yesterday, and we are on spring break.   Most of our client machines are
off.   

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.    

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.  

 

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.


 

Thanks for the tips,

-Dusty-

What and how often do you have scheduled tasks setup for, and how many
clients would hit any of those scheduled tasks at any given time.

I'm wondering if your hitting your JSS too much with the clients.

Which version of the JSS do you have?

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.
 
Thanks
