mm/dd/yy hh:mm:ss LISTENER transactionid taskno IS
NOT ACCEPTING REQUESTS ON PORT port
Explanation
The listener identified by the specified transaction
ID and task number cannot process inbound connections because the
listener's socket descriptor table is full.
In the message
text:
- mm/dd/yy
- The date (month/day/year) of the message.
- hh:mm:ss
- The time (hours:minutes:seconds) of the message.
- transactionid
- The name of the listener's transaction that cannot accept new
client connections.
- taskno
- The task number assigned by CICS®.
- port
- The port number on which the specified listener is listening.
System action
The listener does not accept new connections
until the number of socket descriptors currently being processed by
the listener is less than the value specified by the lesser of either
the system MAXFILEPROC parameter or the listener user ID's FILEPROCMAX
parameter.
Operator response
Contact the system programmer.
System programmer response
Perform any of the following actions
as appropriate:
- If the ERRORTD log indicates that the child server transaction
failed to take the client's given socket, then investigate the CICS region where the child server
transaction runs.
See the steps for
diagnosing TCP/IP clients that are unable to connect in z/OS Communications Server: IP Diagnosis Guide for information about diagnosing child server
transactions problems.
See http://www-01.ibm.com/software/htp/cics/library/ for
information about CICS/TS problems.
- If the listeners NUMSOCK value is greater than or equal to the
value specified by the MAXFILEPROC parameter, then perform one of
the following actions:
- Set the NUMSOCK value to be less than the MAXFILEPROC value using
either the EZACICD macro or the EZAC configuration transaction and
then restart the listener. See
the information about configuring a CICS TCP/IP
environment in z/OS Communications Server: IP CICS Sockets Guide for more information about using the EZACICD
macro and the EZAC configuration transaction.
- Set the MAXFILEPROC value to be greater than the NUMSOCK value
using the SETOMVS system command. See
the SETOMVS command information in z/OS MVS System Commands for information about dynamically changing
the MAXFILEPROC option that z/OS® UNIX System Services is currently
using.
- If the listener user ID FILEPROCMAX value is less than the value
specified by the NUMSOCK parameter, set the FILEPROCMAX value to
be greater than the value specified by the NUMSOCK parameter. For
more information about the FILEPROCMAX specification, see the documentation
provided for the SAF product that is in use on your system. If you
are using RACF®, see the information
about the FILEPROCMAX parameter in the z/OS Security Server RACF Security Administrator's
Guide.
