wodXMPP component (DLL) freezes after calling Connect API (wodXMPP)

Hi,
We are using wodXMPP in our product as a communication channel. Till now we did not face any issues with the component. But recently, we are facing certain issues, where we cannot debug further. When our executable calls the Connect API/function of the wodXMPP component, it just freezes.

Following things were tried to debug the issue.
1> We had provide a time out of 1 minute, but still there is no response after one minute.
2> We checked the anti-virus and firewall settings for exclusion, but it did not work.
3> We further used the telnet command to connect to our XMPP server and it got successfully connected.
4> We also tried to replace with the new wodXMPP component, but still the issue persists.

Thanks & Regards,
Kedar B.

Kedar,

hi. We would need to duplicate this to give you more info. Freezes I have seen before were always related to inability to resolve hostname to IP since gethostbyname API was used which was blocking wodXMPP by winsock stack, until it resolved the host. Not sure if this is happening in your case.

Anyway, do you get same issue with our sample app?

Hi,
Thanks of the quick reply. Let me check with the sample application.

Hi,
I tried to use the sample application provided by wodXMPP,it works on our test system, but it crashes on the client system. In order to find out where it crashes, it is crashing after calling the connect API.

Kedar,

hi. Can you zip your EXE (together with all dependencies it may have) so I can run it here and try it out, to duplicate the crash?

Thanks,

Hi,
Currently I had escalated this issue to my manager, to take further permissions, which will help us to further resolve or diagnose the issue.

Hello WEONLYDO Team,

Let me know if it is possible for you to work on affected systems, we will share the remote session with you.

Once you confirm, we will contact our client and get the schedule to work on the affected system (expected schedule would be, off business hours as per EST time zone)

Please confirm so that we can proceed further.

Hi.

Yes, we could work like that, but I will need VIsual Studio 2008 (or newer) to do the debugging. WIll you be able to provide such environment?

BTW please reply with the ticket at techsupport@weonlydo.com

Regards,
Kreso

Kreso,

We got an approval from my client to install Visual Studio on affected system to debug this issue. Can you please let us know what time will be suitable for you guys (CST time zone) so that I can accordingly schedule this activity.

I have sent an e-mail to 'ticket at' <techsupport@weonlydo.com> too.

Regards,
Zulfikar Shaikh

Zulfikar,
