[squid-users] RE: Squid Restarting Issue

We have an instance of squid - running version 3.0.15 (I know it's fairly old at this stage - but it'll be very difficult to upgrade unless there's a really good reason).

We're getting the below  error in squid - this is happening 10-20 times, where squid throws the error & restarts. It eventually seemed to recover itself.

I've found very old bugs on this on version 3.0-Pre3-20050510, but found nothing since then. Is there a bug logged for this issue - could only find something logged on 3.0pre3 - (bug 879) but it says that it was fixed for final release version. Is this a known issue? Or is there any workarounds we can use for now?

Any help much appreciated.
