squid3 consuming 100% processor

[Colin Law]

Running squid-deb-proxy (client and server) on up to date Quantal, squid3 started consuming 100% of one of processor cores. This has happened twice in the last few days but never previously as far as I know. This continued for around 30 minutes till I re-booted. I don't know what may have triggered it.

If it happens again is there anything I should look at or catch?

I have not so far seen this on Saucy in a few weeks of use. I will add a comment if I do see it on Saucy.

Expericing this bug and was just wondering if anyone has a workaround/solution? Other than upgrading to saucy+ ;)
