Resolution

To resolve this issue, increase the Java™ Virtual Machine memory heap size settings from the default values. For Netcool®/Impact the default value of the Xmx is 2400 MB. In JVM, Xmx sets the maximum memory heap size. To improve performance, make the heap size larger than the default setting of 2400 MB. For details about increasing the JVM memory heap size, see https://www.ibm.com/docs/SSSHYH_7.1.0/admin/imag_monitor_java_memory_status_c.htmlexternal link.
