Pmdtmsvc2 process crash while running EDC profile on ODBC Redshift Connection
Problem Description
While running an Enterprise Data Catalog profile on an ODBC Redshift connection, it fails with "Data Transport Errors" in the Data Quality DIS log. On further inspection, it is found that the core files were being dumped to $INFA_HOME/tomcat/bin. The pmdtmsvc2 process keeps crashing. 
In this case, the DIS had the following DIS custom property set: 


The "M" was missing and must be present. This should be changed to ExecutionContextOptions.JVMMaxMemory=8192M.
Do as follows to resolve the pmdtmsvc2 process crash: 

1. Disable the DIS. 
2. Edit the DIS custom property from "ExecutionContextOptions.JVMMaxMemory=8192" to "ExecutionContextOptions.JVMMaxMemory=8192M". 
3. Enable the DIS and run the profile. The pmdtmsvc2 process would no longer crash.
More Information
the following output is noticed in the core files dumped to $INFA_HOME/tomcat/bin:

MNExecutionContext::getOverrideTracing pointed us to check DIS custom properties and DIS advanced profiling settings. This is where the DIS custom property is present.
