[Freeswitch-users] mod_event_socket 'linger timeout, closing socket'

[Alejandro Recarey]

My bad, I just figured out that linger can take arguments. I was sending
some corrupted data (a space and the null character) and FS took it as a 0,
killing the linger on the first epoch change. I set it to -1 to get
unlimited linger.

Quickly fixed and working, thanks again!
