# bug-1860: Scheduler keeps a job RUN (with allocation) forever after the controller requeued it to PEND while…
|
|
|
|
## Description
|
|
Scheduler keeps a job RUN (with allocation) forever after the controller requeued it to PEND while the scheduler was disconnected: scheduler.log 'JOBS_PUSH: refusing resync state 0x1 for jobid ... -- existing job is RUN with a real allocation on record' on rejoin; job never redispatched (seen in bug-1859's chaotic soak)

## Reproduction

|
|
|
|
## Root cause
|
|
core_events.c JOBS_PUSH bug-1812 guard refuses any non-terminal resync state that would drop a real allocation, to protect against a committed snapshot racing the scheduler's own fresh dispatch. It cannot tell that race apart from a genuine, committed controller-side requeue (e.g. resync 'unrecognized' -> record_job_reconcile_pending_fact) that happened while the scheduler was disconnected, and JOBS_PUSH carries no per-job freshness (commit LSN/version) to decide. Needs a design decision (e.g. per-job last-modified LSN in the push).
