As part of the recent hardware upgrade to my ZFS file server I replaced the motherboard. I'd never replaced the motherboard on an active Solaris system before and was curious whether it would be at the easy end of the spectrum (like OpenBSD is) or at the impossible end (like any recent version of Windows). This is what I learned.
I recently had an issue with an OpenBSD firewall where the number of state table entries was hitting the default limit of 10,000. When this limit is reached, no new state entries can be created. If you're using “keep state”, “modulate state” or “synproxy state” on your rules or if you're running OpenBSD 4.1 or newer (where “keep state” is the default on all rules) this could mean that:
So…. if you hit the state table limit it's kinda bad, mmmkay?
