This is actually MDS4 4.0.5.
On RHEL4 on ia64.
java version "1.4.2_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_14-b05)
Java HotSpot(TM) 64-Bit Server VM (build 1.4.2_14-b05, mixed mode)

This problem is still happening, sometimes several times a week. A very
interesting discovery this morning.
When we get into the wedged state and WebMDS accesses MDS using a hosts
address (info=tgisinfo) everything works fine, BUT when it uses 127.0.0.1
is gets this StackOverflowError.
Restarting the MDS4 container makes this problem go away. Do WebMDS/Tomcat
and/or MDS4 treat 127.0.0.1 differently?
I've now confirmed that does not have anything to do with using a normal host
address vs 127.0.0.1.
Whichever address is being used primarily between WebMDS and the TG WS MDS4
container can get in this wedged state.
As of this instant. The following is an example of the error.
Attached is the failure output.
