Bad page error from dmesg
 

Hello,
I sometime see the following message from dmesg, I don't know what is wrong.

any suggestion is very appreciated.

sc2dadh is a data handling task, which waits on semaphore, gets data from memory, process data and sends/receives message bewteen other process.

{
Bad page state in process 'sc2dadh'
page:c1800000 flags:0xc0000400 mapping:00000000 mapcount:0 count:0
Trying to fix it up, but a reboot is needed
