Hello DHIS2 -

We are seeing a similar condition as referenced in archived message
:#03464. The solution offered was to restart Tomcat.  Periodically, our
users cannot access DHIS and we will need to reboot the server.  Msg 03464
implies that we cannot run multiple instances of DHIS on the same box and
that this may produce a memory leak.  We are wondering what is the source
of the memory leak as referenced in #03464  (and as shown below) and if
this could cause our system to lock up ?

Thank you for any help.

SEVERE: The web application [/dhis218] appears to have started a thread
named [GT authority factory disposer] but has failed to stop it. This is
very likely to create a memory leak.
