Subject MFCF UI Hangs
Date Mon, 10 Dec 2012 08:17:43 GMT
Hello.

I started with Manifold CF5.1 and noticed that when the web crawler is
running, at some point, the admin UI admin UI hangs.

I thought that it may be due to the embedded java db.
So upgraded to PostgreSQL and still seen similar problems.

Now, I am running on MFCF1.1 on PostgreSQL 9.2 and still same issue.

When a click on any of the links such as
List Output Connections
List Authority Connections
List Repository Connections
List all Jobs etc

The UI takes a very long time and than I see nothing but the blue screen as
shown at

Note that after I restart, things are OK for a while...

This is on a fresh start of jetty, and the only one error in the log file
is shown below.

My Java version:
java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) 64-Bit Server VM (build 23.1-b03, mixed mode)

I have also captured a thread dump that can be seen at
