Some of the jobs doing ABAP extracts from DataStage have a dump in SAP in ST22. This is during the extract from SAP. So the job is running from 3.08AM and there are 18 mil rows to be pulled. The dump says it has come across a communication error at 5.14. The exact error is Error when opening an RFC connection ("CPIC-CALL: 'ThSAPOCMINIT' : cmRc=27

Is there any resolution that anyone knows to this issue? Does it need a fixpack from IBM or is it a config change on SAP side to add a retry to that TP?

Is it the complete log? Did you try to check the SAP side logs? Timeouts are very common while fetching data from SAP. And this may be related to that. in case you do not have access to SAP side, do you see any pattern like the jobs aborting exactly after same time duration like 30 mins from job start or something similar?
