I now stays up thanks, though I can't work out how to be sure it's doing anything since it doesn't have a log file. Check out Squid's log file. Accesses from 127.0.0.1 will be from the prefetch.

Accesses from 127.0.0.1 will be from the prefetch. Not necessarily. 127.0.0.1 is the network loopback device, so *any* program on that machine which accesses the outside world via squid will show as 127.0.0.1 in the squid log, not just squid-prefetch as you imply.

True. I don't use the loopback interface for connecting to squid from user clients, so I don't have that ambiguity. You can usually differentiate between clients and squid-prefetch by the log line itself. The first access by squid-prefetch will always be a TCP_HIT/200 or TCP_MISS/504 (I think it's 504). After that will be the prefetches. Or... just run it from the command line so you can see STDOUT.

I will report on whether squid-prefetch now stays up. Any luck? (Please Cc: the bug on replies.) It is running now, without dying. I haven't replied because it's now being hammered by my search engine's spider - and I want to wait and see if it stays up during that.

Alarm clock
It seems the alarm timer isn't getting reset in case of exceptions.
Does the attached patch work for you?
Thanks!

Package: squid-prefetch Version: 1.0-1 Severity: grave Justification: renders package unusable I found that the program will only run for a few minutes before it stops.
