Thanks for your response Giovanni. Yes are not Skype instances, but Xvfb instances and FS start working after several restartings. But now we are starting to get issues when FS went down regularly. It is strange because gateway worked fine long time ago. We already tried: 1) reboot full box a lot of times. fs works ~5 min (i can make a calls) and down again. there is nothing interesting in the fs logs. I only see that error in mesages May 8 10:16:11 SkypeGW1 kernel: freeswitch[6220] general protection rip:2b1848474c31 rsp:2b1858b9e400 error:0 2) tried to change skype id. we only have inbound traffic and some people said that microsoft can prevent correct work of gw in this case. so they advised to change skype id but that didn't help. 3) we have script which does full re-creating skype configuration of skype instances after restarting of box. This way we prevent issue with high PCU usage of skype instances. I believe you know that i talking about. 4) we have core dump and can open jira ticket if this is the correct way. Please advice Thanks.

I would try killing all Xvfb ("# killall -9 Xvfb"), restart Xvfbs and Skype clients, then restart FreeSWITCH. If this does not works, let us know.
