Hi,
Is this any good at all or do I need ro provide more? It seems a trivial issue to restart a browser but the bigwigs are climbing all over me now! 

Cheers

Alex

We are also getting a lot of this sort of thing in the logs since I've patched that Assert. Not sure If it's related.

Brilliant! I will try to apply this and see if we get more detail. Will
it apply to 3.2.x? I can't run 3.4.x in prod due to the CPU load issue - and I only see the crash in prod, never managed to trigger it in a test. 


Yes it should apply on 3.2, though I have not tested that.

dying from an unhandled exception: c

I just realised what is generating this is a "Must(c)". There are only
two of them Squid, but unfortunately in the generic and widely used
CbcPointer template.

Can you apply this patch please and see if we get a useful backtrace
next time:
http://www.squid-cache.org/Versions/v3/3.HEAD/changesets/squid-3-13386.patch 


(this will also be in 3.4.5 to help with future issues hidden by the
same message).
