# X_DEV_STOP_TIMEOUT

## Means

x stop sent SIGTERM and x dev did not exit in time

## Typical cause

the x dev the checkout lock names is still running when the wait ends: a drain past its deadline, or a process that ignores SIGTERM

## Fix

`x stop --timeout 2m --json`; still running: `kill -9` the pid its cause names, then `x dev --json` (a hard kill leaves the lock, which the next boot clears)
