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
