11.0(1.10000.10)

Description (partial)

Symptom:
High memory usage on CAR Scheduler (carschlr) during auto-purging of partitions. 

From "top" command: 
  PID USER      PR  NI %CPU    TIME+  %MEM  VIRT  RES  SHR S COMMAND 
9182 ccmservi  17   0    6 142:11.79 14.8  459m 300m 7116 S carschlr

Possibly, the "OutOfMemoryError" message can be caught in the CAR scheduler traces. And/or Total JVM memory usage is close to Max JVM memory allocated for CAR scheduler. For example: 
... JVM status: [Max = 246.56MB, Total = 244.88MB, Free = 3.87MB (1.58%), Used = 241.01MB (98.42%)]
...OutOfMemoryError seen somewhere during CAR Loader Run - Round #2648

Conditions:
When MAX_CAR_DATABASE_AGE setting is set lower than 34 (31+today+2) days, and loader is actively running with relatively light traffic. This setting is controlled via the CAR admin System -> Database -> Configure Auto purge page. Max Age of Call Detail Records below 34 days can lead to this condition.
