System dump compression
Default compression of system dump isn't turned on, which may cause a lot of error report entries about your system dump devices being too small.
Check if the compression is on/off:
# sysdumpdev -lWithout compression, sysdumpdev -e will estimate the system dump size.
To turn compression on:
# sysdumpdev -CThis will reduce the required (estimated) dump size by 5-7.
