Plesk 7.5.2 firewall issue

[bdobson]

We have a Plesk 7.5.2 server which in the past week has had a periodic issue with the firewall. We have added no rules to the system aside from the ones which are there by default. The machine locks up and spews this message:

ipfw: install_state: to many dynamic rules

It is a FreeBSD 5.3 OS.

It doesn't appear to be Plesk-related, but more along the lines of limits in the FreeBSD kernel for the stateful firewall. Follow this link and see if it helps.
