What issue are you seeing?

I have many agents with the same CODEX_HOME coding in parallel. But out of the sudden I ran into a race condition (at starting a new codex session):

Codex couldn't start because another Codex process is using its local data.
Quit any other copies of Codex that may still be running, then try again.
Technical details:
  Location: /home/mf/codex-cli/state_5.sqlite
  Cause: failed to initialize state runtime at /home/mf/codex-cli: failed to open state DB at /home/mf/codex-cli/state_5.sqlite: error returned from database: (code: 5) database is locked: error returned from database: (code: 5) database is locked: (code: 5) database is locked
ERROR: failed to initialize sqlite local db at /home/mf/codex-cli/state_5.sqlite: failed to initialize state runtime at /home/mf/codex-cli: failed to open state DB at /home/mf/codex-cli/state_5.sqlite: error returned from database: (code: 5) database is locked: error returned from database: (code: 5) database is locked: (code: 5) database is locked

Could you please add the PID of blocking process? This message doesn't help, I need to know which process is blocking so I can kill it. Also, locks should be timed out automatically if there is no running queries. If the process has the DB locked, and it is not alive, you should drop the connection and put the DB in unlocked state

What steps can reproduce the bug?
