squidaio_queue_request: WARNING - Queue congestion?

http://ocsp.entrust.net/MEUwQzBBMD8wPTAJBgUrDgMCGgUABBSgLXLbL4La7i%2B3dMpUpZCcZtKubgQU6r8QpQEelY%2FJVbRnYKSP%2FYsPErQCBEKHQKU%3D";?

Given that it appears to be decreasing on the expected pattern, it seems to be the ignorable case.


storeAufsOpenDone: (13) Permission denied ?

Now that one appears to be nasty. Squid does not have privileges to open one of its own files.

Given that it is followed by congestion warnings, I'm thinking the disk controller is busy doing something to the disk, maybe its an AV or integrity scan of some sort or simple put the drive into hibernation for a short while.

The result of this is either that something is not deleted when it should be (BAD). Or that something is not saved to disk when it should be (not too bad, just means a TCP_MISS later on).

How frequent are these and is there any other signs of what is going on?

Oh, and the usual: what version of Squid is this?
