SAP Note 15372 - SAPcomm: error after SAP System restart

Symptom:

SAPcomm error after SAP System restart.
Various SAPcomm error messages, e.g.
E0011: Error write queue.
Component error: get sapcomm.mid semaphore.

Cause and prerequisites

Operating system resources (semaphores, etc.) have been deleted.

This may be due to the following reasons:

1) The resources were deleted by operating system commands (iprcm
or corresponding commands).

2) The resources were "automatically" deleted due to shutdown of a
running SAP System. This is only possible when the same computer
runs both SAPcomm and the SAP database, application, or presentation
server. If this is the case, the cause of the problem is an
error in the SAPcomm configuration.

Solution
Delete any running SAPcomm processes and existing SAPcomm resources (shared memory, semaphores, event flags, and system queues):
SAPcomm programs: Operating system command "kill".
Shared memory, semaphores
and event flags: SAP program "cleanipc ", "no."
is the number of the "SAPSYSTEM"
from SAPcomm profile file sapcomm.pfl

System queues: Operating system command "ipcrm".

Re Cause 1):
You should never delete operating system resources that SAPcomm is using while SAPcomm is running.

Re Cause 2):
The root of the configuration error: SAPcomm and an SAP System have the same value for profile parameter "SAPSYSTEM". Set this parameter (in sapcomm.pfl, the SAPcomm profile file) to a value that is not used by any SAP System.
