I would think this would be the root issue: "Too many open files"
We dont have much file handling operations in our web applications,
but again I am going to look minutely all IO operations in my
application.
What OS are you running. Some limit the number of open file
handles. Also might want to check to be sure you are closing files
when finished with them in your webapp.
its running on *Red Hat *Enterprise Linux AS 4. I am at all not good
at system programming, but I would love to know any such
commands/utilities exist that can tell me detail about what are the
files getting opened in my web application which results such exception.

Hi Experts,
I am facing a strange problem in my tomcat
application. Suddenly it generates following Exceptions
java.io.FileNotFoundException:
/server/http/site/music.yamaha.com/site/work/SESSIONS.ser (Too many
open files)
at java.io.FileOutputStream.open(Native Method)
..
....
And some other application FNF
java.io.FileNotFoundException:
/server/http/site/ssd.com/site/dist/tilesCopy/en_US/siteTree.xml
(Too many open files)
at java.io.FileInputStream.open(Native Method)
...
...
What might be the possible causes that generates such exception?
Some people suggested me to check whether application is running on
development mode, and if yes then change it to deployment mode i.e.
<context-param>
<param-name>configuration</param-name>
<param-value>deployment</param-value>
</context-param>
I am not using any <context-param> in my web.xml.
I would appreciate your thoughtful suggestion.
regards,
Ranjan

To see your current settings use 'ulimit -a'. If you want to make
permanent changes edit /etc/security/limits.conf
Everything in a system is a file, not just a single webpage, the default
are not enough for your requirements.
