Error description
SVC probes observed to hang, which drives up memory usage and causes the device server to encounter an OutOfMemory condition. The resulting heap dump file contains StackOverflowError Exceptions. In the probe logs SVCs report a high number of datapaths, which might be the reason for the large number of mapper-instances: SVC-2145-xxx_SVC1-IBM (0000020xxxxxxxxx) with xxxxx datapath instances and SVC-2145-xxx_SVC2-IBM (0000020xxxxxxxxx) with xxxxx datapath instances HWNEP0001I Successfully persisted 8 rcrelationship instances. HWN021719I Perform collection post process tasks for storage system.
