    FMS 4.5 crashing. Shared memory heap has exceeded 90 usage.

      FMS is crashing with the following errors:

       

      2011-12-06  10:24:02    12461   (w)2581227  Shared memory heap (__FCS__) has exceeded 90 usage. Consider increasing the heap size to prevent future memory allocation failures. -

      When I try to restart I get:

       

      2011-12-06  17:33:27    7933(e)2781340  Process 7933 failed to create IPC queue __FCS__ : Failed to allocate shared memory. -

       

      I've noticed the problem resolves when I restart fmsadmin. I think fmsadmin is using up all the shared memory, not sure. There are HTTP requests periodically being sent to fmsadmin, could this be a source of memory leak?

       

      The server has 6 GB RAM and there are only about 100-200 connections being used. Runs without issues most of the time, crashes once every few days.

       

      What is the shared memory heap and how do I increase it?
