Binary package hint: clamav

# apt-cache policy clamav-daemon
clamav-daemon:
  Installed: 0.96.3+dfsg-2ubuntu1.0.10.04.2
  Candidate: 0.96.3+dfsg-2ubuntu1.0.10.04.2

Since the security update of clamav, the daemon takes multiple minutes to load its virus database, and is causing random timeouts for users of the unix socket (in my case, mimedefang), trigger 400-series email temp-fails.

strace just shows it slowly allocating memory and not doing much else.

Logs don't seem to help:

Thu Dec 16 20:58:34 2010 -> clamd daemon 0.96.3 (OS: linux-gnu, ARCH: x86_64, CPU: x86_64)

Thu Dec 16 20:58:38 2010 -> Loaded 856324 signatures.

But minutes later, it's still spinning at 100% CPU and non-responsive on its socket.

Debug symbols seem incomplete for some reason, but here's the backtrace while it's stuck, FWIW:
