Found 75-126 stale `occ system:cron` processes on 172.16.3.22 piling up
since 2026-04-27 due to bad oc_filecache LIKE query against pavon's 257K
camera files. Killed stale procs (load 80 -> 5), wrapped apache crontab
with `flock -n /tmp/oc-cron.lock` to prevent restacking. Per-user
versioning disable rejected by OwnCloud Community (`files_versions`
can't be enabled for groups); workaround `occ versions:cleanup pavon`
identified and deferred. Migration/retention cron deferred per user.
NVR architecture clarified: GeoVision NVRs sync via OC Desktop client
with virtual file placeholders; no direct SMB access to Jupiter.
