Error description
BPM process containing javascript which attempts to serialize or deserialize String data that contains incorrect CDATA form (e.g missing "]]>" from <![CDATA[sometext]]>) may result in high memory usage and CPU consumption if the process is allowed to continue. . This is what the heapdump would show in terms of the memory usage. . A Linked List Data Structure Detected. 4,591,895,664 bytes (78.34 %) of Java heap is used by 95,664,492 instances of java/util/LinkedList$Link Contains the following object: - 95,664,491 instances of com/lombardisoftware/core/VariableObjectSerializer$CDATALocation holding 2,295,947,784 bytes 4,591,895,712 [24] 2 java/util/LinkedList$Link 0x4b188c38 |- 4,591,895,640 [24] 3 java/util/LinkedList$Link 0x4b189330 | |- 4,591,895,592 [24] 3 java/util/LinkedList$Link 0x4b189390 | | |- 4,591,895,544 [24] 3 java/util/LinkedList$Link 0x4b189468 | | |- 24 [24] 1 com/lombardisoftware/core/VariableObjectSerializer$CDATALocation 0x4b189450 | | |- 4,591,895,640 [24] 3 java/util/LinkedList$Link 0x4b189330 | |- 24 [24] 1 com/lombardisoftware/core/VariableObjectSerializer$CDATALocation 0x4b189378 | |- 4,591,895,712 [24] 2 java/util/LinkedList$Link 0x4b188c38 |- 48 [24] 3 java/util/LinkedList$Link 0x1aced9f50 . .-------------------------------------------- This java exception may be logged as well java.lang.OutOfMemoryError at java.lang.Object.clone(Native Method) at java.lang.reflect.Method.getParameterTypes(Method.java:265) at com.lombardisoftware.utility.spring.TransactionInterceptor.invok e(TransactionInterceptor.java:37) at org.springframework.aop.framework.ReflectiveMethodInvocation.pro ceed(ReflectiveMethodInvocation.java:171) at com.lombardisoftware.utility.spring.CoreEntryInterceptor.invoke( CoreEntryInterceptor.java:44) at com.lombardisoftware.utility.spring.PSCoreEntryInterceptor.invok e(PSCoreEntryInterceptor.java:14) at org.springframework.aop.framework.ReflectiveMethodInvocation.pro ceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkD ynamicAopProxy.java:204) at $Proxy29.findByFilter(Unknown Source) at com.lombardisoftware.server.ejb.persistence.PersistenceServicesB ean$6.execute(PersistenceServicesBean.java:122) at com.lombardisoftware.server.ejb.persistence.PersistenceServicesB ean$6.execute(PersistenceServicesBean.java:120) at com.lombardisoftware.server.ejb.EjbServerUtils.handleEjbCall(Ejb ServerUtils.java:90) at com.lombardisoftware.server.ejb.persistence.PersistenceServicesB ean.handleEjbCall(PersistenceServicesBean.java:49) at com.lombardisoftware.server.ejb.persistence.PersistenceServicesB ean.findByFilter(PersistenceServicesBean.java:120) at com.lombardisoftware.server.ejb.persistence.EJSRemoteStatelessPe rsistenceServices_ccd74654.findByFilter(Unknown Source) at com.lombardisoftware.server.ejb.persistence._PersistenceServices _Stub.findByFilter(_PersistenceServices_Stub.java:546)
Local fix
Correct the invalid CDATA tags.
Problem summary
**************************************************************** * USERS AFFECTED: BPM user on v8.0.1.1 * **************************************************************** * PROBLEM DESCRIPTION: Invalid CDATA string in javascript * * may result in OutOfMemory error and * * high CPU usage. * **************************************************************** * RECOMMENDATION: * **************************************************************** Incorrect form of CDATA string in javascript can cause OutOfMemory error and high CPU usage.
Problem conclusion
The code has been corrected to recognize the invalid CDATA string. ‚   When an invalid CDATA string is encountered, the BPM engine will issue a WARNING message, and the invalid CDATA string will be omitted from the serialized output. Install/Dependency information is available in the readme.txt on FixCentral. When the user goes to the download files page in FixCentral, the readme will be available with the fix package as a separate download.
Temporary fix
The CDATA string should be corrected to have the proper end tag "]]>". ‚   This will avoid the problem.
