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.
