The servers are behind a loadbalancer, each of these servers handle
about 20k unique users a day.
I've included two graphs (Load Average and Memory Usage) from one of
these application servers. The shibd process is being restarted 2 times
a day, at 12u15 and 03u15. 
Today, for example, the daemon was restarted at 12u15 and the memory
usage has reached 2,3GB.

We use the default memory session cache. The cacheTimeout is reduced to
600 seconds. 

Are you planning to make SRPMS for the new Xerces library?

Kind regards,
