Thanks Anthony,
I can provide the Dump for you it’s 8gb unzipped so I’ll compress it. The tool I use is Visual studio but I’m sure there are other tools too.
I can run a the profiler tool in visual studio to find the CPU.
Also how do I get the modified copy of the APR?
Thanks again guys.
Andre

The cond waits are all of your session threads in bypass media mode asleep in the state machine.
Its hard to tell with that blurry screen shot what else is going on. Is there a way to produce that data in a way we could browse it?
You should be looking for threads in the sofia sip stack and the ones doing originate if you are worried about pdd. Also which threads are costing the most CPU. If conditionals are implemented in windows as waitforsingleobject i have no idea if that's as efficient as it is in linux.
You could try forklifting in our modified copy of APR that has been updated to work with their latest release and see if anything has improved in the windows implementations of conditionals. I recall Jeff had to backport in at least one patch for that over the years.

Ok I’ll try that next. I’ll create xml dialplan to see if that makes a difference.
One note, when I didn’t load the deck in my managed code my dial plan did return a 503 in 0 – 20 milliseconds. Not sure if that matters since no bridge was ever called.
Thanks again,
Andre

I would test this without any of your managed code at all, to confirm that it is not the bottleneck.

It seems it might be stuck in the condition code for Windows.
Try this timing patch for Windows, and see if it makes any difference. I've tested in on lower load, but it would be interesting how it performs in this scenario.

I will, need to get hardware and figure out how to use mono.
In the meantime, I’ve attached some of the call traces.

Try the same thing on Debian 7 if possible.

Hi, I’m using the master. Should I try 1.4.7?
I’ve done a dump after things started to go bad/ backed up.
I see 8193 threads in _*thread_cond*_timedwait. Looks like its on line 81 of thread_cond.c res = WaitForSingleObject(cond->semaphore, timeout_ms);
The value of timeout_ms is 2016850392.
Not sure if this means anything.
Thanks for the support guys.

1.2.X is EOL,
1.4.7 is the current release.
We have releases and tags in git that no longer carry the 'stable' moniker starting with 1.4.

We dont have a lot of tools to troubleshoot windows. You should mention windows in your subject to have a better chance to get the attention of our windows users.
You should consider installing debian 7 on the same hardware and perform similar tests to help determine if your issue is o/s specific or not.
You also have not indicated the revision of FS. If you have not worked with latest master, you should be also to rule out improvements.

Yes that's off and I believe all the databases are off too. No authentication or registration is enabled. The sizes of the database are 0 until I call the shutdown command then its about 90k. I have the DBS in Ra drive too.
Windows seems pretty good until the 3000 sessions per min mark. Then I just get long pdd and the threads get backed up then no more sessions can be created.
Funny thing is I has 10 profiles and the same results. I also tried two consoles with the same results.
FreeSWITCH is great.
I'd be grateful for help. I've worked on this for 2 years and hate to give up.
If any one from consulting@freeswitch.org is willing to help I'd appreciate that.
Thanks again, Andre ------------------------------

Did you comment out manage-presence ? Also we have no real idea how well FS performs in windows under extreme load.

Going with the idea it’s IO related I did a db_cache status. I just disabled limit in my code by removing it but limit should be HASH not a database however I stills how a database.
Below is the results of the db cache status. I’m not real sure what its saying. I should have all registration and limit disabled and should not be using any sql database from my understanding.
Anyone know what the results mean? I’ve only tested 2 calls on this status.
