Enterprise Client Community

Hi Community,

on the customer site we've the problem that the apache tomcat is crashing every 6 hours.
In our application running on this server we're using the longpolling component. We have noticed, that it seems to be that the apache is not able to close some long polling processes (see screenshot). Maybe this is the problem, why the apache is crashing.

somebody an idea?

regards thomas

Hi,

the only thing I can imagine - currently - is:

(.) you have a lot of clients, each one with an active LONGPOLLING - then you have to increase the number of threads...
(.) you do not destroy long pollings properly.

The long polling thread is closed when...
1. you pass back a long polling via LongPollingMgr.remove(ILongPolling)
2. you call ILongPolling.wakeup(false) or ILongPolling.abortThread()

Could you check?

Regards, Björn

I think we're closing the long polling.
On serveral installations (other customers) it is working well.
Remarkable is, that the most entries are from the same ip address.

Is it possible that the proxy has something to do with this issue?
Maybe the client is closing, but the proxy is keep alive the session/thread?

Thanks for your help in advance!

regards Thomas

Hi,

if you properly close/remove ILongPollong within your program then the corresponding threads should be removed, with or without proxy... ;-)

Otherwise: they have to somehow "time out", and maybe there is some influence by a proxy... (exactly in the direction you describe).

Björn
