[Asterisk-Users] RE: chan_unical-MFC/R2 CPU usage problem

[Hadi Jadallah]

Hi,

My variant is standard ITU, I tried almost all versions I could put my hand on to no avail.
I tried also to profile the channel and related libraries to no avail as my profiling skills on linux are abit lacking.
If anybody with this problem and knows how to profile multithreaded apps on linux then we might at least pinpoint the location of the error.
I cant realy put the machine into active duty if I cant solve the problem.

Btw, what version of libtiff are you using? It difficult to believe that it might be related as I don’t need the fax functionality. Mine is the version that comes with CentOS 4.1 which is 3.6.1.

Hadi.
