RFC error text: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'

13251 Views

I am having this error pop up very frequently on some new SAP systems. This will randomly happen and keep us from being able to release transports and import them in STMS. I receive the following error:

There was an attempt to start the transport control program tp using the local RFC interface.

An error occurred here.

Error code: 4

RFC error text: timeout during allocate / CPIC-CALL: 'ThSAPCMRCV'

- When I check the Transport Tool (STMS: import queue > check > transport tool) I get the following information:

timeout during allocate / CPIC-CALL: 'ThSAPCMRCV' : cmRc=20 thRc=456#Time

out during connection setup (check that partner exists

- When checking the TP System Log I receive the same error. The RSTPTEST report does not give any additional information. SM21 shows a warning and an error:

Warning:

Communication Error, CPIC return code 020, SAP Return code 456

Dialog Process No. 000

Problem cl: SAP web AS problem

Package: STSK

Further Details:

Module Name: thxxhead

Line: 7488

Error Text: 020456

Caller: ThRecei

Error:

Problem cl: transaction problem

Package: STTO

All of these errors are only pointing to a time out. I cannot figure out why this is happening. I checked the TMS RFC connection in SM59 and they are fine. I have been able to work around this issue in 2 different ways. First, I can delete the files in the "\trans\tmp" directory on the server. Sometimes this resolves the error. Else I have to restart the system.

I need to understand where this issue is coming from and how to resolve it. It is becoming more and more frequent. Thank you for your help!
