Switching to runlevel 1 does not reclaim anything. After 20 days of uptime it will occupy more than half the memory, forcing the system into a grinding halt due to excessive swapping. # n=0; while :; do n1=$(awk '$1 == "size-4096" { print $2 }' /proc/slabinfo ); if [ $n -ne $n1 ]; then printf "%s\t%d\n" "$(date)" $n1; n=$n1; fi; sleep 2; done Mi 24.
