Question

Hi,
During idoc processing we see following messages generated in SAP system log which complain that the servers are getting disconnects from message server..
SM21 ::
Error found in PBT environment, FM = SPBT_GET_CURR_RESOURCE_INFO
> Failure checking whether server is active/inactive
Documentation for system log message EK 1 :
While processing parallel background tasks, the system discovered an
error in the specified function module. The reason for the error is
described in the corresponding system log entry.
Failure checking whether server is active/inactive
Documentation for system log message EK 5 :
While processing "parallel background tasks", the system could not
determine whether the application servers involved are active or
inactive. This is possibly because the connection to the message server
was lost.
Please help me to resolve the issue.
Thanks and Regards
Mohsin

Hello.
May be I had the same problem, because in sm21 i saw analog message.
As it appeared the qrfc (smqs) scheduler has problem (smqs - monitor) whith one of the instance included in my group:
Name of AS Group (DEFAULT = All):        parallel_generators
In transaction sarfc we founded the problem instance. This instance had red status "Error in configuration". We removed the problem instance from group parallel_generators. After this qrfc  scheduler worked succesfully.
The instance had problem because parameter "Activated (0 or 1)" = 0 (sarfc configuration of qoutes). If you change this parameter to value 1, you can include the instance back to group.
