 how to fix it ?

Environment

Endevor Web Services V18.0.12

Resolution

Solution: 
1) Increase the allowed maximum JAVA Heap memory usage - modified the JVM option in WSTOMENV (if JVM setting allow enough memory to run the application, no java dump will be created)
2) In java program, turn off writing of Java dump.   
3) Correct the allocation error (check the disk space and give permission to allow user WSTOMSTC to create/write to the temp dataset)
