hmmm syslog-ng relies that it gets an error when it tries to send to an
already closed TCP connection. (basically it expects an EPIPE), can you
check whether the clients get this kind of error? (using strace, truss
or ktrace)

a quick workaround seems to be to enable keep-alive() on your tcp
sources, this way the TCP connection will not be closed, however this
would not solve the caswe when you stop and start syslog-ng.
