Asunto: Re: [SR-Users] EOF Error in pass_fd

Hello,

there was a wrong unlocking of the profile while printing its content via MI, that could caused a race and eventually this kind of crash (in the case a dlg was added/removed in/from profile while the mi command was run).

I committed a patch, you have to use latest branch 3.2. Let us know if all goes fine now.

Cheers,
Daniel

Hello List.

The last weekend our kamailio process crashed with this error :
