High CPU usage in DMP 4400

Level 1
Level 1

We encountered high CPU usage for a number of DMP 4400 running on ver 5.2.3 that caused the display to be very slow and sluggish. We found that the high load is due to task /user/bin/sysmng job which is taking 99.8% of the load. Even after we do factory reset on the DMPs, the load on some DMPs still remain high.

Anyone has similar experience? Any explanation what can cause the sysmng to take up so much of CPU and how should we recover?

Hi Lam,

Which type of content are you running on the DMP? Did you review the content creation guidelines specs:

If the content you are running is following the specs, I would recommend to open a Service Request with TAC to investigate further the causes of the high CPU.



Hi Marco,

Thanks for your reply and informaion. We have done some trouble-shooting and found that the high CPU occurred after we enable RS232. We also found the following errors when we do get param command. Attached is the complete log. Not sure if you have any idea on the errors?

Hi Lam,

You can most likely ignore those error messages, they look unrelated with this problem and most likely cosmetic.

I would recommend you to open a TAC Service Request at  this point, I am not aware of other situations where High CPU is  triggered by RS-232 usage, so this would need more in depth  investigation.
