We would need some more information about syslog-ng when in this bad
state. Please attach to the syslog-ng process with strace right before
sending a HUP signal and wait till some mail log is generated.
Use the following strace command:
strace -s 256 -o /tmp/output-file -p <syslog-ng pid>
And an idea, isn't it postfix that stops logging?
