    No performance problem here.
    It is just letting you know that if there is an OS crash and it has to dump its memory there is not enough space in the filesystem to fit the dump in to.
    Check out the sysdumpdev command to find out how much space you might need (sysdumpdev -e) and the -l switch to find the dump fs.
    Increase the fs or create a dedicated dump fs to allow a dump if you are ever likely to need a dump analysed, if not then do not worry about these errors.
