Tony and Andre, Rather than going back and forth on this matter, here are the instructions on how you can find out exactly what is going on. On your target system, make sure you have the sysinternals tools installed, and in your path. This will enable you to use procdump from the command line. When FS gets into the state with an assload of hung threads, use procdump to take a full dump. This will be a very large file. Copy the .dmp file from the target box, to the build box, if they’re the same then forgot about copying it. Now on your build box, open the FS solution in VS. Then in VS from the File->Open menu, open the .DMP file. This will put  you in the debugger, just as if you were running FS under a debugger. Check the Threads windows and see if a buttload of threads are all hung in the same place. Double clicking on the thread will push that thread into the call stack window. Now you can see where the thread is hung. If it’s in a kernel call go up the strack till you get to code in FS. Double click on that stack frame, that will open you to the line of source code at the point it got hung. In the source window it’s just like in the debugger. Hover over any variable to see it’s value. This is the same process for doing it under linux, but rather than using GDB you have the full VS GUI debugger experience. Tony, you can quote him the same if he gives you access to the build box, as you would for someone that gave you access to a dump and GDB. Because you most likely will have a lot of threads all hung in the same place, and threads call stack, and source code are in different windows, this should take about 10 minutes to find out what’s going on. --Dave From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Anthony Minessale Sent: Sunday, August 17, 2014 2:53 PM To: Freeswitch-users Subject: Re: [Freeswitch-users] high pdd When you refer to more getting performance as getting it fixed, it strikes a nerve. Start with what I said and test for same results on debian 7 to have clarity if you have a windows specific performance limitation. There might be up to 1 million lines of code difference between windows and *nix. We can't even tell you how much to pay unless we know there is something to change. Also there is no indication you are using realistic traffic to test. All of these details are critical.

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.

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.

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.
