Andras Bacsai ed979f42ef Fix SSH multiplexing contention for concurrent scheduled tasks (#6736) ... When multiple scheduled tasks or database backups run concurrently on the same server, they compete for the same SSH multiplexed connection socket, causing race conditions and SSH exit code 255 errors. This fix adds a `disableMultiplexing` parameter to bypass SSH multiplexing for jobs that may run concurrently: - Add `disableMultiplexing` param to `generateSshCommand()` - Add `disableMultiplexing` param to `instant_remote_process()` - Update `ScheduledTaskJob` to use `disableMultiplexing: true` - Update `DatabaseBackupJob` to use `disableMultiplexing: true` - Add debug logging to track execution without multiplexing - Add unit tests for the new parameter Each backup and scheduled task now gets an isolated SSH connection, preventing contention on the shared multiplexed socket. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>		2025-12-05 09:54:30 +01:00
