Problem

When trying to view a job that has a large amount of data contained in the sysout, the gateway goes into state NO SYNC. This has caused us to miss a newdayload on a few occasions. Re-starting the Control-M Server on the affected environment fixes the problem, as well recycling the gateway on the affected environment.

The gateway loses sync/communication with the M/Server after an attempt to view a sysout. In the gtw_log, a disconnect is visible and that corresponding service is visible in the CO debug, which times out. Just prior to this is a larger instance which relates to viewing sysout. The M/Server and EM GTW my be recycled to resume communication.

[31@14:03:12.170:] ===> ERROR: Sync req: 135449009 with DEV timed-out 500 sec. connection close
[31@14:03:12.170:] ===> ERROR: EM-29001E: GTW - GTW Service Timeout.
EM - CONTROL-M DEV Communication Service Timed Out. timeout=503, type=Sync, instance=135449009.

Cause

Solution

1. Logon Control-M/Server as Control-M/Server User

2. Navigate to <Control-m_server_install_dir>\ctm_server\data

3. Make a copy of config.dat file

4. Find below entry in the config.dat file:

CTM_MAX_IPC_Q_SZ 10000

5. If you can't find it, add above line to the end of the file.

6. Change the line to:

CTM_MAX_IPC_Q_SZ 30000

7. Save and exit.

8. Restart Control-M/Server to make effect.(shut_ctm, start_ctm or use ctm_menu)
