Total: 3 years and 51 days of uninterrupted uptime for this Cisco PIX 515e, and pushing traffic the whole time.
If it wasn't rebooted to update the OS, it would be easily 5+ years of uptime.
It's doubtful that the longest uptime is an encouraged achievement. There are probably multiple exploits that are going unpatched.
Unfortunately, we will be retiring this firewall for a new ASA 5510. As much as it's dumb to fix what's not broken, we need to keep up with newer software/security. One of my worries about keeping the PIX is a situation where it's so old it's unsupported or unable to transition the config over to new firewall because so much has changed.
