Could it be the Timer is waiting for a previous action to finish? Maybe the FTP
connect 'hangs'.

I have an app running in Tomcat 5.5.12, with jre 1.5.0_12 (explicitly
specified in the service configuration), on windows 2000 server.
I have one class that is initialized by a servletContextListener, in the
contextInitialized event. This class uses java.util.Timer and
java.util.TimerTask to check every few minutes for new files on an ftp
site, and if it finds any, it downloads and processes them. This all
works fine for anywhere from 2 or 3 days to a week or so, then the timer
just stops firing, and indicated by a sudden lack of entries in the log
file (I log every time the timer fires to help track down this problem).
Over the last couple of weeks, I've found some things that can cause
this, but I believe I've fixed them, but my timer still stops firing
after a few days. The things I've already fixed were updating the jre
to 1.5.12, because of problems with automatic time correction on the
server, and I found that unhandled exceptions in the timer task can also
cause this, so early last week I modified my code to trap all exceptions
before they can trickle up to the timer, and log them, and I don't see
any exceptions being logged.
It doesn't seem to be related to the number of executions, because the
latest time it stopped on me, it had fired around 1200 times, and the
time before that was around 4500 times. It can also be any time of day,
and sometimes the server is busy and other times it hasn't had a
connection for several hours.
Any other suggestions as to what I should look for to find this?
Thanks!
