KAVU2228-E

Connection processing timed out during TCP/IP communication. (connection destination host name: destination-host-name, IP address: IP-address, port number: port-number, system error number: system-error-number)

A timeout occurred when a connection request was issued to the remote host during TCP/IP communication for job execution control.

(S)

Cancels the requested processing.

(O)

One of the following problems may have occurred in the connection destination host. Check the following and correct the cause of the error, and then reissue the request.

  1. If JP1/AJS3 at the connection destination has not started, start it.

  2. Check whether the port numbers used for submitting a job match between the manager and the host where the job was executed. If JP1/AJS3 links to another system such as JP1/NQSEXEC or JP1/OJE for VOS3, also check whether the port number in the services file is correct.

  3. If you changed the default gateway while JP1/AJS3 was running, stop the JP1/AJS3 service, and then change the default gateway.

  4. Check and, if necessary, change the setting so that the IP address of the logical host and that of the agent belong to the same network. Also see 2.3 Determining the network configuration in the JP1/Automatic Job Management System 3 System Design (Configuration) Guide to specify the setting for communication using multiple network addresses.

  5. Recheck the setting of the network, including hardware, for a problem in the network. For example, execute the ping command to check whether communication is possible.

  6. For a cluster configuration, if the system is set up so that the logical IP address is released before JP1/AJS3 stops when a failover occurs, correct the setting so that the logical IP address is released after JP1/AJS3 stops.

  7. Note that if you specify too small a value for the connection timeout, retry count, or retry interval, a communication error cannot be prevented due to a too short retry interval for communication. This may cause the error to occur frequently.

    Normally, the connection timeout value is set to 90 seconds. For details about how to change the connection timeout value, see 6.2.8 Changing the timeout period, interval of retries, and number of retries for TCP/IP connections in the JP1/Automatic Job Management System 3 Configuration Guide (for hosts under Windows), or 15.2.8 Changing the timeout period, interval of retries, and number of retries for TCP/IP connections in the JP1/Automatic Job Management System 3 Configuration Guide (for hosts under UNIX).

  8. This error might occur if a larger number of job-start and job-end notifications are output in a short period. If there is no problem with the network, and this error occurred because a large number of jobs to be executed are concentrated in a short period, take action such as distributing the number of jobs to be executed during the period. Such an action will prevent a large number of job-start and job-end notifications from being output in a short period. Generally, this error might occur when 50 or more jobs are executed per second for the physical or logical host of the manager.

    To check the number of jobs that were executed in the short period during which a large number of job-start and job-end notifications were output, check the number of KAVS0263-I messages that were output to the scheduler log file during the corresponding period.
