Openfire 4.6.4 out of memory

Openfire Openfire Support
#1

Hi all,

We are using the 4.6.4 on product, but it will throw out of memory after running for a while. After dump the Java heap, we find there a lots of Deliverable objects in HttpSession.

My question is why there are so many Deliverable objects in HttpSession. Can we delete these objects by any settings ?

Thanks,
Joe

This there a reason you are using this version versus the current release of 4.7.4 ? Your problem may just go away with a current release. There have been fixes since 4.6.4 to httpbind and memory management.

Hi Joe,

As akrherz suggested: try upgrading Openfire first.

These Deliverable instances keep track of the data to be sent to clients that are connected using HTTP-Binding/BOSH. If Deliverable stack up, then there might be misbehaving clients (that for some reason do not collect enough of the data that they’re being sent). What client software are you using?

#4

Hi guus,

Sorry I miss you answer. We are using the strophe JS library as our client.

Thanks,
Joe

#5

And BTW, do you have any sample code for strophe ? because we just use it as http bind function, other functions are all implement by Java code.

Thanks
Joe

I don’t have example code of how to use Strope, sadly. There are enough projects out there that use Strophe on Openfire with success, so I don’t expect that to be much of a problem.

I’m curious: If you’re using Java for all other functions, then why did you choose a Javascript library for the HTTP binding bit? Aren’t there Java libraries up to the task? Our own Smack library offers support (although I believe that in the current 4.4.6 release, that’s considered of ‘beta’ quality).

#7

Hi guus,

I also confuse about this ( only use the Javascript for HttpBind ). Because I am the maintainer of this system, we will not change the framework too much now. So by now the best is upgrade openfire to 4.7.4, right ?

#8

Hi guus,

Another question, do you have any work around to delete the pending items for version 4.6.4 ?

No, this problem is new to me. I’m not even sure if upgrading to the latest release will help - but I think it’s your best chance.
