RE: [squid-users] Squid Restarting

Thanks Amos - we have heap dumps but unfortunately we could not share with the wider community as they're taken from a customer production environment. However, we can send on information taken from the heap dump - like output from pflags/pstack/etc. Would this be sufficient to investigate the issue?

Thanks and regards,
Justin

Seems to be new and a bit strange. Squid opens one connection to the server to fetch content sometime later a connection was closed, but not the one which was opened to begin with.

Do you have a core dump or stack trace available to identify what the fd and server_fd values actually were during the crash?

Being the first report over a month after the release, it would seem to be very rare.
