Description

Tried turning on trace:

>networkservercontrol trace on
Invalid reply from network server: Insufficient data.

The server process shows the following stack trace:

access denied (java.io.FilePermission Server58.trace write)
java.security.AccessControlException: access denied (java.io.FilePermission Server58.trace write)

The server now does not respond to ping or shutdown, and has to be killed.
