vsish -e get /memory/comprehensive

memstats -r group-stats -g0 -l5 -s gid:name:parGid:nChild:min:max:minLimit:conResv:availResv:memSize -u mb 2> /dev/null | sed -n '/^-\+/,/.*\n/p' | awk 'NR == 2 || $2 ~ /(vim|vimuser|terminal|ssh)$/ {print $0}'

vsish -e get /sched/groups/767/memAllocationInMB

Set new limit
