[squid-users] Squid 3.1.16: Startup problem on OpenBSD 4.9

Hello!

Sometimes starting Squid in OpenBSD 4.9 fails with the following message
in cache.log:

> diskHandleWrite: FD 10: disk write error: (14) Bad address

So far, I was unable to get some more information when enabling some
debug options. The only bit of information I was able to gather was a
ktrace:

The error is unfortunately hard to reproduce. One of about 10 startups
the problem occurs.

Thanks for any advice!
