RE: Non-Responsive

Here are some current results:

 

When max sockets are reached the following behavior was noted:

 

For this test I had the following conditions set:

 

1.) I used screens to create a separate session window on Linux and set ulimit to be 60 sockets for gnugk to run with.

2.) I had signaling handlers set to 15 and with h225 routed and h245 being tunneled. No media proxying.

3.) I was able to create 3 telnet instances to the status port and on the 4th instance I got a blank telnet response. This meant I ran out of sockets

    which is the state I wanted gnugk to be in.

4.) When I issued a reload on one of the telnet sessions all endpoints that were registered suddenly unregistered.

5.) I retested the same case scenario and this time had a segmentation fault (core dump).

6.) I performed the following test a few times over and the same scenarios played out, with endpoints un-registering and segmentation fault happening.

 

 

I'm in the process of creating some test with the call generator and see what the behavior is when calls are being sent to the system when max sockets are reached.

Hi Todd,

 

That's interesting. I was thinking of maybe running the call generator

program that comes with openh323 and setting the ulimit for total

sockets on gnugk to a very small number like 20, then generating like 50

or more calls at the same time using the call generator. Maybe like this

we can duplicate this behavior and see if this is the actual problem. I

will try later on today if I find something and post my findings.

Something that was noticed was that the GNU had a ton of sockets in wait

state.  It looks like there was a blip in IP and these sockets did not

get

released and the GNU had them in wait state.
