[Nottingham] Cups slow problem

[John]

The bug is interesting, but the latest Centos patches don't fix the problem. The original server hadn't been patched for donkeys, so at a loss why it started happening, just need to fix the bugger. There's the odd network error, but nothing worse than normal.
