FOP 2.26 suddenly stops

marco.capetta

Hello,

We have several installations of FOP 2.26 on FreePBX 2.9: all work well and there were no problems.
Only by a client we are notified that about once a month FOP2 suddenly stops and they are no longer able to login to the web interface. When I connect I note that the service is actually stopped.
I tried to enable debugging, as you have indicated in several posts, but given the rarity of the problem I could not pick up anything interesting.
After a few months, the issue is becoming quite critical.

Do you have any suggestion or solution to the problem?
The version 2.27beta could solve the problem? Since this is a "beta" I can make sure that there are no other instabilities that could worsen the situation of our client?

Thanks
Best regards
Marco

The only known crash in 2.26 is related to websockets over a large installation. Disabling websockets in /var/www/html/fop2/js/presence.js will fix the issue. Upgrading to 2.27 beta will also fix the issue. If that is the case, if you start FOP2 in debug mode via options file, then you can quite clearly see the error with not much work, just edit /etc/sysconfig/fop2 and set it like

OPTIONS="-d (and whatever other options you might have) -X 4 -l /tmp"

Debug level 4 is not verbose, so you can keep it running for several days and it won't produce a large output, in /tmp you wil end up with the output.log file with no useful data, and the error.log file that will contain the actual error for a crash, if what you are experience is indeed a crash. If you see "payload to big", it is the websocket issue I mentioned and is fixed it by disabling it or upgrading.

Hello,
thanks for the quick response. I will try as soon as possible to enable debugging and eventually to disable websocket.
I would point out also that I noticed something else quite curious: when I restart FOP2 after a crash, I find that the license is disactivated. Thus, I have to reactivate it manually. Is this the normal behavior?

P.S. When it is scheduled the final release of FOP 2.27?

Thanks again
Best regards
Marco

It is not a normal behavior to have license problems, unless your server changes network settings or mac addresses on the fly. If you notice the license is not working, run /usr/local/fop2/fop2_server --test , the output will give an idea on what could be wrong.. perhaps you do not have a fixed hostname?

Hello,

I disabled the websocket and enabled the debug.
For now, all right, we will see in the coming days.

Thanks for the support.
