Longest Open TCP Connection?
I thought it would be fun to run this submission fromivan256 who asks: "I was sitting at my desk noticing that i had be telneted between my linux boxes for 16 days, and it got me wondering... What would be the longest continuously open TCP connection? Is it still open?" I'd highly doubt this has actually been recorded, but I'm sure you guys have personal records you wouldn't mind bragging about.
We had a production server that was up for 497 days, 2 hours, and 27 seconds before crashing itself about a week ago. Apparently the version of the Linux kernel it was running wasn't able to handle the "jiffy roll" problem -- sort of a little mini Y2K where the jiffy timer counter in the kernel overflows its 32 bits. At that point, two processes (cron and some at job) started spawning violently and brought the load average up to about 15, when it promptly died from a disk controller problem ;-).
Before that, we were afraid to reboot the thing because we didn't know if it would come back up right, and it's been up for so long that it's been up longer than I've been with the company. It still had an early version of Debian 2.0 with kernel 2.0.35 =). We were planning to run its UPS down to my car and plug it into a power inverter to get it somewhere without shutting it down, but alas, that isn't neccessary now. ='| =)
