Zimbra 8 - java.lang.ClassFormatError: Truncated class file

Question

We have been getting java.lang.ClassFormatError: Truncated class file since yesterday for our Zimbra server based on Ubuntu.

Despite that nothing is changed; everything had been going well until yesterday. Now the web user interface of Zimbra is not rendered; we get 500 internal server error in Firebug.

Any ideas to solve this problem?

Do a file system check (e.g. `man fsck`). Check the class file (or JAR file) that the exception messages says is corrupted. Then try to figure out how your system got into that state. — Stephen C, Dec 29 '14 at 06:18

Your server is setup on default configuration.

It unpacked your war file into the system temp directory, likely /tmp.

Some other process then cleared out the /tmp/ directory, rendering your active runtime invalid.

See other answer about setting temp / work directories for more information.
