Users dissappearing after upgrade to 3.9.3

After I upgraded from 3.9.1 to 3.9.3, users are randomly appearing offline, even though they’re not actually signing out.

I first heard about this issue here

http://community.spiceworks.com/topic/493600-spark-users-disappearing-after-3-9- 2-update?page=1#entry-3328488

Anyone else have the same issue?

Maybe you are running out of JVM memory. There is a memory leak in 3.9.2/3.9.3 (actually it is in 3.9.1 also, but not so big) https://community.igniterealtime.org/thread/52516 So maybe your server is reaching the limit and users start to pop out of the server. Does the server restart helps with the issue for some time?


I just checked memory usage in Task Manager and I’m only at 96,700Kib (been running about two weeks now)

I will restart the server and see if I see any changes.

You should check main page in Admin Console. Refresh it repeatedly to see what a maximum peak of jvm memory is.

The highest it’s been is 35mb. A server restart this morning did not really change that number and it did not fix/alter the problem of users dissappearing.

Well, i haven’t used 3.9.3 long enough to notice such issue probably (only a few days). Maybe the same as 2. issue here https://community.igniterealtime.org/message/239750#239750

Yes, it is the same thing. That’s at least three people that have the same issue

I wasn’t sure to split up my post but yeah. I’ve kept my eye on the memory usage and it keeps jumping consistently all day. If I do a ‘top’ at the Linux console java is using about 11% of the total memory, about 2116m VIRT, 211m RES and 13m SHR. So it’s not using too much but the java VM still oscillates (memory leak) and needs to be debugged.

I defintely have the same issue here, we upgraded and everyone in the enterprise here has noticed the issue. We run ours on a windows machine. I think this is a bug that is pretty widespread it seems.
