Hi,
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.
Regards,
Justin
You are the first to hit it again since then.
Is your squid patched with old patches written prior to 3.0 perhapse?
There should be a core dump sitting around from the crash which you can
use to figure out what the real problem behind the crash is. You need to
know that to find a workaround or fix.
