5.5.16, Too many open files on startup
Hi,
I have a server.xml with 37 virtual hosts defined, each with 1 root context
also defined in the same file (yes, not recommended, but not explicitly
disallowed either, right?).
Tomcat starts up fine and is solid with this config on 5.5.15, but not on
5.5.16.
After 14 loaded contexts on 5.5.16, I get "Too many open files" errors, and
exceptions like:
Apr 10, 2006 5:56:23 PM org.apache.catalina.startup.ContextConfig
processContextConfig
SEVERE: Missing default web.xml, using application web.xml only
conf/context.xml /usr/local/tomcat/conf/context.xml
java.io.FileNotFoundException: /usr/local/tomcat/conf/context.xml (Too many
open files)
That context.xml is in place and contains default values.
I did notice that a change was made between 5.5.15 and 5.5.16 that may have
something to do with this (from the ChangeLog):
Deploy folders which don't have a WEB-INF, and return an error when a
context file does not contain a Context element (remm)
Not sure why folders without a WEB-INF are being deployed now, as I have
many folders that contain static content that I certainly don't want
deployed as webapps.
Also, I'm on Linux, and my ulimit is set to unlimited.
Any help greatly appreciated.

Re: Setting up to use 443
Posted by Dhaval Patel <dh...@yahoo.com>.
Hi,
Couple of things:
1) Make sure you change 8443 to 443 on all places in server.xml (there are 2 places.)
2) Make sure that no other service running on 443 port. This way Tomcat can use that port.
3) What tomcat version you are running? Do you want to use APR?
Now I dont know which version of tomcat you are running. If you are running tomcat with version
5.5.x, you might have to enable/disable APR to use SSL. For more information, please visit my post
at : http://www.mail-archive.com/users%40tomcat.apache.org/msg02500.html
Steps described in the link above WORK 100%. However steps ONLY work with self-signed certificate.
It does not work with Versign/Thwatte Signed certificate. So just to keep that in mind.
Let me know how it goes.

Nothing shows up on the logs.
On Mozilla, this alert is displayed - "The connection to localhost has
terminated unexpectedly. Some data may have been transferred."
Not sure what data you want from TCPView, but accessing https shows a
TIME_WAIT state for that process when it is using port 443.

Can you tell us the exact error? Internet Explorer throws up that error in
a lot of situations. This could be the result of a firewall or another
process on 443. Anything show up in the logs? Can you try it with Firefox
for a better error display? TCPView from SysInternals can show open and

Can you tell us the exact error? Internet Explorer throws up that error
in a lot of situations. This could be the result of a firewall or
another process on 443. Anything show up in the logs? Can you try it
with Firefox for a better error display? TCPView from SysInternals can
show open and connected ports as well.

Refer to this tomcat documentation page for ssl configuration: http://tomcat.apache.org/tomcat-4.0-doc/ssl-howto.html
Edit the server.xml accordingly. While editing the file, you have to correctly specify your realm. Then restart the tomcat.
Good luck.
