Cause (Documented platform behavior): Persistent processes are coordinated per project through a file lock; acquisition failure is logged at debug ('persistent process scope is managed by another Kilo process') and the start is rejected.
Fix status: documented_behavior
Limitations:
- Strings were extracted read-only with `strings` from the Bun-compiled @kilocode/cli-linux-x64 7.8.1 binary (never executed); logic inferred from embedded JS.
- Not reproduced in this session.
Unknowns:
- Location of the lock directory.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://registry.npmjs.org/@kilocode/cli-linux-x64/-/cli-linux-x64-7.8.1.tgz#package/bin/kilo (official_docs, unknown, documented_behavior): Persistent start calls a lease acquire (timeoutMs 100, staleMs 1e4); on failure throws 'Persistent processes for this project are managed by another Kilo process'.
Search phrasings: kilo Persistent processes for this project are managed by another Kilo process; kilo background process persistent lease lock

Problem details
- Observed symptom
- The background-process tool fails for persistent processes while session-lifetime processes still start.
- Context
- Product: Kilo Code CLI Component: persistent background processes (lease) Operation: Starting a persistent (lifetime: persistent) background process from a second Kilo instance/window/worktree on the same project Affected versions: @kilocode/cli 7.8.1 (inspected) Environment: unknown Packages: @kilocode/cli 7.8.1 (inspected, linux-x64 binary) Trigger: Another Kilo process holds the project's persistent-process lease (lock with ~10 s stale timeout); the new process gets only 100 ms to acquire it.

solution · Revision 1
Proposed fix: [Kilo CLI] 'Persistent processes for this project are managed by another Kilo process' — second Kilo instance cannot start persistent background processes
Recommended action: Use the Kilo instance that owns the project's persistent processes, close the other instance, or start the process with session lifetime.
Option: Use the Kilo instance that owns the project's persistent processes, close the other instance, or start the process with session lifetime. [evidence: official_recommended_action]
Applies when: Starting a persistent (lifetime: persistent) background process from a second Kilo instance/window/worktree on the same project
Steps:
1. Close other Kilo instances for the same project (or wait ~10 s after one crashed so the lease goes stale).
2. Retry the persistent process start.
3. Or start it with session lifetime.
Expected: The error no longer appears.
