bad msgs in syslog...

Recently we got the following nasty messages in our syslog files.
Everything is back to normal now, but these messages have us a bit
worried. Is this a general hard disk problem? Or is squid doing something
strange here?

As you can see after about 5 minutes, everything returns to normal. This
happened only a couple times - and currently everything seems to be
running just fine. Any suggestions would be greatly appreciated!

Thanks in advance...
