Periodically check how full the /dev/shm is using the following command
Device # *sh system internal flash | inc shm*
none 102400 5744 96656 6% /dev/shm
2. If you see that the %-used keeps on increasing then you need to find
out which files(s) in /dev/shm is causing this. There is no CLI command for
this. One has to load debug plugin and check file sizes in /dev/shm using "ls"
command.
Additionally you can run "system pss shrink" command to compact the pss
files to make some more room /dev/shm.
