[Freeswitch-users] mod_event_socket message pizza received from BSD machines

[Anthony Minessale]

I don't know what latest snapshot you are talking about but I am
saying to try GIT HEAD by checking it out and building.
When you say "we handle" do you mean you wrote your own client interface?

The exact symptom you describe is a bug recently fixed in the ESL
client code due to a missing null termination on packets read into the
buffer.  If you are not using libesl, there is no way the socket
itself should be messed up.

When you say only BSD or MAC do you mean running the server or the client?

> We ran the load test this morning on latest snapshot.tar.gzip on FreeBSD 8.1 64-bit and on latest nightly windows 64-bit binaries. Works well on windows, pizza on BSD / OSX. Don't think it is related to ESL-56, since we handle the case where events arrive before replies, our problem is that event and reply seems to be 'merged' corrupting the protocol.
