Hi all,

Our EP7 was extremely slow this morning. We found 2 threads in our server process as RUNNABLE. Both threads were the same, does anyone know what this is?

Dear Patrick,

The problem could be as well an endless loop due to corrupted Hashmap.

Hi Patrick,

I happened to stumble upon this:

Note 625509 - Enterprise Portal hangs with almost 100% CPU usage
