I've had an issue come up where the DMPs across the system will start having black screens between images, then load the images slowly. The black screen is just a symptom of the slowdown. A reboot resolves the issue, but it returns after about a month. It isn't restricted to one group or another. If I let it go long enough, it happens to all the DMPs in the system.
Is there a more permanent solution or best practice other than scheduling a reboot once a month?
DMPs are 4400G with 5.3 firmware.
Possible issue and solution\workaround other then rebooting
- Problem could be related to syslog misconfigured in default configuration causing browser to block. This can be worked-around by the following MIB changes: init.syslog_collector change to 127.0.0.1 (Default is 192.168.1.1) Using DMPDM: If syslog is disabled, enable it and set the syslog server address to 127.0.0.1, disable it, save and restart the DMP. Using DMM: create a task to change the syslog server address to 127.0.0.1 and deploy to all DMPs. - Disabling video failover will improve transition time. - Enable Caching on the DMP
You may want to look at some of these options and use an extra DMP to test and see what happens
