[Freeswitch-users] Seem to be attacked, CPU rate 95%, stop working, no log output.

[Eric Ni]

I can't see anything as the log stopped. As to those been logged, no sign
of excessive sip message. Statistics from the Linode VPS also show a normal
traffic volume. It look like a fs problem, but I don't know how to debug or
report it as no log and no core dump.

By the way fail2ban is already configured.
