Summary 0001375: mod_caucho starts returning 404s on all resin handled requests
Description We have several load balanced web servers running apache and mod_caucho on resin 3.0.21. When we send the servers kill -HUP during log rotation ocassionaly a server that has been up for a long period of time (>30 days) will start sending out 404 errors on all requests that resin is handling. Values mapped via plugin_ignore are handled properly by the Apache server. Sometimes if the apache server is restarted the problem goes away other times it does not go away no matter if I kill -9 the process and restart. The problem always goes away if the server is completely rebooted. The server is configured via the ResinConfigServer directive.
Additional Information Server: Apache/1.3.37 (Unix) Resin/3.0.21 mod_ssl/2.8.28 OpenSSL/0.9.8b
2.6.8-2-386 0000001 Tue Aug 16 12:46:35 UTC 2005 i686 GNU/Linux

A failed request looks like this (I changed some values to placeholders 'x' ):
xxx.xx.x.x - [xx/Sep/2006:xx:xx:xx -0700] "GET /index.jsp HTTP/1.1" 404 - "" "Mozilla/4.0 (compatible; MSIE 6.0; AOL 9.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)" "-" 0

And a File does not exist shows up in the apache error logs. The other webservers in the cluster run fine. One thing that's kind of odd is that there is no data sent back when the 404 hits.

As a workaround, you might look at the /tmp/*_6802 files and delete them when doing an Apache restart.

That wouldn't fix the initial problem, but would let you restart Apache without rebooting the machine.
