Description (partial)


An extremely slow memory leak in the CSAuth process gradually consumes memory on the ACS
Solution Engine.  The memory is tied up by the CSAuth process and it gradually uses more
memory after each replication cycle.  Over a long period of time and several replication cycles,
this eventually can use all available memory.

This can be a difficult issue to spot directly as it is specific to the ACS Solution Engine and
these devices don't have direct access to tools such as performance monitor.  Also making
diagnosis difficult is the fact that routine operation of the ACS has expected "spikes" and "valleys"
in csauth memory usage that well exceed the size of this memory leak.  However, in an affected
device, over a long period of time and several replication cycles, the "reports and activities",
"appliance status page" should show a slow trend of decreasing available physical memory.
