4: ZRPC-EVT-SLR-ERR
Probable Cause
A call to the NonStop TCP/IP Sockets Library Routine (SLR) failed or returned an error.
The value returned for the Z-ERROR field in ZSPI-TKN-ERROR within the error list
indicates the cause of the error. This value can be interpreted as follows:

Values in the range 301 through 342 indicate a NonStop TCP/IP socket error.
NonStop TCP/IP socket errors are defined in the ZTCPIP.PARAMH source file. For
descriptions of the NonStop TCP/IP socket errors, see the TCP/IP Management
Programming Manual.

Values in the range 0 through 255 indicate a file-system error. File-system errors
are defined in the ZFILDDL source file. For descriptions of the file-system errors,
see the Guardian Procedure Errors and Messages Manual.
The most likely cause of this event is that the NonStop TCP/IP process was
inaccessible because either the process was down or the network connection was lost.
Recommended Action
The recommended action depends on the cause of the error:

If the error indicates that the NonStop TCP/IP process was inaccessible (file-
system error 201 or 250), the portmapper process records the event, closes all
open sockets, and then periodically tries to reestablish communications with the
NonStop TCP/IP process for a configurable period of time. If communications are
reestablished, the portmapper process reopens its sockets and proceeds as usual.
If communications have not been reestablished after the configurable period of
time, the portmapper process abends, and operator intervention is required to
restart the process.

If any other errors occurred, refer to the locations indicated previously for the
appropriate recovery procedures. All other errors are considered fatal and cause
the portmapper process to log the event and abend.
