I have a dedicated server running CentOS 5.9, Apache-Tomcat 5.5.36. I
have written a JAVA web applications which runs every minute to collect
the data from multiple sensors. I am using ScheduledExecutorService to
execute the threads. (one thread for each sensor every minute and there
can be more than hundred sensors) The flow of the thread is
1. Collect sensor information from the database.
2. Sends the command to the instrument to collect data.
3. Update the database with the data values.
There is another application that checks the database every minute and
send the alerts to the users (if necessary). I have monitored the
application using jvisualVM, I cant find any memory leak. for every
thread. The applications work fine but after some time(24 Hour - 48
Hours) the applications stop working. I can't find out what the problem
could be, is it server configuration problem, too many threads or what?
This might not be a Tomcat server problem but this could be!!!!
Does anyone have any idea what might be going wrong or is there anyone
who has done think kind of work? Please help, Thanks

This may be a naive question, but from your description above it is not clear if any of
these applications have anything to do with Tomcat, or with a webserver environment.
Why would it/they be running "inside" Tomcat ?
