nv_faxdetect module cannot be load

Hi Everyone,

I'm facing strange problem right now.
One of my client having TB 2.8 installed from CD and recently I've run yum update on it, since then the problem begin.
The server was configured from the start to receive faxes by email with NVFax detection, but not longer after update clients ring me and said there was no incoming calls for that day and no problem with outgoing.

After short investigation I've found that incoming route become unusable and asterisk did not process any calls. The only way to fix it was to recreate incoming route with no fax detection.

Checking asterisk log I've notice that app_nv_* modules are not loading any more

[Feb 22 16:07:56] WARNING[20419] loader.c: Error loading module 'app_nv_backgrounddetect-1.0.6_1.4.so': /usr/lib/asterisk/modules/app_nv_backgrounddetect-1.0.6_1.4.so: undefined symbol: STANDARD_USECOUNT

and trying to load them manually failing as well.

Digging out Internet did not give any answer, hoping here I can find someone with more experience that I have.

Kind Regards,
Yuriy
