| My JVM is erratic and/or I see java.util.zip.ZipException errors in my logs. |
| Answer |
Tomcat in it's default configuration tries to auto-decompress
and auto-deploy *.jar files you drop into place in the various
directories it keeps watch over.
Normally this is great, but what we've discovered is that if it
sees a new file, and the file is in the process of being uploaded
(IE, slow scp or ftp link) then Tomcat will try to decompress
it, in the process corrupting it.
After that, Tomcat will disable the webapp that the JAR was deployed
under, as well as trying to re-decompress it every couple of
minutes. Each time failing, and each time leaving behind a mess
of unclosed processes and/or files.
The ultimate result, if not caught in time, is a server crash.
There are a couple of ways to work around this problem. One is
to disable the auto-deployment features. Another is to upload
the files to a temporary directory, then using the command line
(via SSH) you can move the complete file into place. Yet another
is to stop your Tomcat JVM before doing the upload, then start
it after the upload is complete.
