[Bug 523610] Re: rsyslogd spins CPU on some kernels

[Callum Macdonald]

I had what I believe to be the same issue on 12.04 Precise 2.6.32-12-pve
x86_64 running in a Proxmox container. I downloaded
http://archive.ubuntu.com/ubuntu/pool/main/r/rsyslog/rsyslog_4.2.0-2ubuntu8_amd64.deb,
installed, and now the error messages are no longer appearing.

Does this bug need to be re-opened? A new bug filed? It's showing fix-
released but apparently the issue (or a variation) still exists.
