Dead processes accumulation causes system resource exhaustion #56
Description
Description
svim accumulates zombie (defunct) processes over time, eventually exhausting the system's process limit. In my case, ~1982 zombie child processes accumulated, hitting the macOS default maxproc limit of 2666 and causing fork() failures across the system.
Observed behavior
$ ps -eo ppid,pid,state,comm | awk '$3 == "Z" {print $1}' | sort | uniq -c | sort -rn | head -5
1982 1095
$ ps -p 1095 -o pid,ppid,comm,command
PID PPID COMM COMMAND
1095 1 /opt/homebrew/op /opt/homebrew/opt/svim/bin/svim
Killing svim immediately reaps all zombies:
# Before: 2808 processes
$ kill 1095 && sleep 1 && ps aux | wc -l
818
