The squid (2.7) proxy that I have running on ubuntu 8.10 stops accepting new requests after being online for a while, due to reasons that I can't discover. However doing a squid -k reload resolves the problem immediately.

Now I manually run this command by monitoring the log and if i don't see any activity for 5 minutes I reload the config.

Now on my quest for a solution I had several ideas:

diagnose the root cause and eliminate it
setup a script to automatically reload script if no new entries in access.log for the past 3 minutes
painstakingly upgrade server to newer ubuntu version while keeping network offline or during off hours to minimize downtime.

so i thought I would turn to you for solutions to option 2), as I do not understand squid enough for 1), and I'm avoiding 3) as long as i can. so can ideas?
