Java freezing up JSS - Which version of JSS

[jhalvorson]

Which version of the JSS do you have?

(EDITED on 03-29-2013: removed extra words that were needed from my original post.)

[dustydorey]

Casper Suite 6.01

Web App memory set to just a tick under 2GB

Database Size: 1.7 G

Max Packet size set to 6MB

Tomcat Min. Memory 256; max 2048

Server has 8Gb total

Dusty,
I increased the Mac Packet size to 16 MB at one point and that seemed to help.
I also have up to 4480 MB Ram available to tomcat.

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.

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,

We have this issue as well and have found that we are hitting the JSS to
hard with Policies that run at startup. I have made some changes to the JSS
as recommended below and will advise on the outcome.

We were having the issue with the JSS freezing up when our scheduled
task to report in would run. We bumped from 8GB of RAM to 32GB of RAM
and gave the max to web app and now we're good to go. No issues.
That was on a leopard server running casper 6.01 and in 64 bit mode.

On the issue of Java crashing, has anyone upgraded to the lasted Java
release 7 for 10.4 Server and had any problems or improvements?

Ben.
