[Devel] help needed debuging TLS

[Klaus Darilion]

Hi!

I'm still debugging the reported TLS crash. Currently I wonder about 
different logs. I've installed openser-cvs on 2 different servers(both 
debian 3.1 with same kernel, one is my hetzner server, the other is a 
local vmware server).

The test scenario is connecting with eyebeam in TLS mode and then kill 
eyebeam which cause a TCP RST packet sent to openser. On one server 
(vmare) this also causes a SIGPIPE (13), but not on the other server.

I do not know if this can be related with the TLS crash, but anyhow does 
someone know how this can happen on one server, but not on the other?
