Yourkit.NET freezes the application all of a sudden

Post by svenkataraman »

Hi,
Is there any known issue with the YK.NET agent dll freezing the host application at times?

We took some dump using userdmp tool when one of our application got frozen for no reason. Some data I am pasting below on this:

!cx 00000001`80171bf0 ynpagent!Java_com_yourkit_Natives_getWinRegSubKeys+0x00000000000c3040

dt ntdll!_RTL_CRITICAL_SECTION 0x00000001`80171bf0
+0x000 DebugInfo : 0x00000000`00181520 _RTL_CRITICAL_SECTION_DEBUG
+0x008 LockCount : 0n-154

+0x020 EntryCount : 0
+0x024 ContentionCount : 0x2d357
+0x028 Spare : [2] 0x740066

Critical Section is LOCKED, with 38 Waiters

Hello Sathish

Which version of the profiler do you use?

Could you please invoke "Help | Collect Information for Support..." in the profiler main menu and send the results to [email protected]

Best regards,
Anton

Yourkit.NET 5.0.7

We used a evaluation key, and we are trying to purchase few licences, now this crash is concerning us as we may not be able to do profiling until this is resolved.

The agent dll along with our product is freezing, not the UI that is used remotely. What information(Help | Collect Information for Support) will this fetch for you?

Thanks

Yourkit.NET 5.0.7
This version is unsupported.
Please use version 6.0.x instead.

If you need another evaluation license key for version 6.0.x, please write to [email protected]
The agent dll along with our product is freezing, not the UI that is used remotely.
The action "Help | Collect Information for Support" runs 2 applications:
- <profiler installation directory>\bin\YourKitInfo32.exe
- <profiler installation directory>\bin\YourKitInfo64.exe (if it is a 64-bit machine)

You can run the applications manually in console on the problematic machine and redirect the output to a text file.
What information(Help | Collect Information for Support) will this fetch for you?
It's a technical information about system version, installed .NET frameworks, installed profiler agents, profiler logs etc. - everything that can help us understand why the agent does not properly work on your system. The information is stored to a local text file on your system, it is not automatically transferred to YourKit. You can browse that text file before sending it to us to ensure that it does not contain any sensitive information.

Sorry, We got the issue using yourkit 6.0 too on another environment. We have uninstalled it due to eval expiry, I got the extension in eval now, so will get the info you want.

Btw, we have a dump taken by userdump(MS tool) during the frozen state, you want that?
Should I be discussing this here in this forum or with your support?

Thanks

Yes, could you please send that file attached as a reply to the email with evaluation key which we've sent to you.
