Error message
PowerShell 进程探测超时（{}ms） What it means
powershell_output_with_timeout spawns a PowerShell process to probe running processes and enforces a wall-clock timeout. If the child does not finish within the timeout, it is killed and an io::Error of kind TimedOut is returned with the elapsed milliseconds in the message. Callers use it to enumerate codex/antigravity/codebuddy processes on Windows.

Solutions
- Increase the timeout passed to powershell_output_with_timeout if the machine is known to be slow.
- Retry the probe once; transient stalls often resolve on a second attempt.
- Add -NoProfile -NonInteractive to the PowerShell invocation to avoid profile-load delays.
- Check system load / antivirus interference with powershell.exe and WMI/CIM service health.
Example fix
// before
let out = powershell_output_with_timeout(&cmd, Duration::from_secs(5))?;
// after
match powershell_output_with_timeout(&cmd, Duration::from_secs(15)) {
Ok(out) => out,
Err(e) if e.kind() == std::io::ErrorKind::TimedOut => {
log::warn!("powershell probe timed out; retrying once");
powershell_output_with_timeout(&cmd, Duration::from_secs(15))?
}
Err(e) => return Err(e),
} Defensive patterns
Strategy: retry
Try / catch
match powershell_output_with_timeout(&cmd, timeout) {
Err(e) if e.kind() == std::io::ErrorKind::TimedOut => retry_with_longer_timeout(),
other => other,
} Prevention
- Invoke PowerShell with -NoProfile -NonInteractive to avoid startup delays
- Budget timeouts for slow machines and antivirus scanning of powershell.exe
- Retry transient timeouts once before surfacing an error
- Keep WMI/CIM services healthy on Windows probes
When it happens
Trigger: Calling any of the collectors (collect_codex_process_entries_from_powershell, collect_antigravity_process_entries_from_powershell, collect_codebuddy_process_entries_from_powershell, close_processes_by_exact_exe_paths, collect_codex_windows_resource_process_pids) when the spawned PowerShell child exceeds the configured timeout.
Common situations: Slow or loaded Windows machines, PowerShell cold-start/profile-loading delays, antivirus scanning powershell.exe, Get-CimInstance queries hanging under system pressure.
