Comment 3 for bug 392077

Confirmed by at least 3 Ubuntu users in this bug report:

http://pad.lv/392077

However, the report is rather old, so its possible this has been fixed in newer releases. Here is the original description from the original reporter:

Squid3 commonly crashes several times a day with no apparent reason. Up until now I used squid which worked fine. This happens after upgrading to squid3.

In /var/log/squid3/cache.log, the last lines are:
2009/06/25 13:10:51| ctx: exit level 0
2009/06/25 13:10:51| clientParseRequestMethod: Unsupported method in request '^C'
2009/06/25 13:10:51| clientProcessRequest: Invalid Request
2009/06/25 13:12:52| assertion failed: store_swapout.cc:317: "mem->swapout.sio == self"

In syslog, this is reported:
Squid Parent: child process 20916 exited due to signal 6
