…GOMEMLIMIT, MOM responder) The production VMs are hand-managed (no startup-script/IaC), so the manual system-level state applied during the 2026-07-24 outages had no version-controlled home. Capture it so it survives reprovisioning: - pilot-service-agents /etc/logrotate.d/pilot-agents + hourly cron (prevents the /var/log/pilot-* disk-full → jbd2 hang → fleet outage that recurs in ~5 days without it); - pilot-rendezvous-new GOMEMLIMIT=48GiB drop-in; - MOM box responder topology (C++ responder kept, Python planner disabled; sync_and_reload.sh target).

The production VMs (
pilot-rendezvous-new,pilot-service-agents, the MOM Lambda box) are hand-managed pets — no startup-script or IaC. The system-level fixes applied during today's outages therefore live only on the boxes and would be silently lost on any reprovision. This captures them as a committed runbook.Most important:
pilot-service-agentslog rotation — without/etc/logrotate.d/pilot-agents+ the hourly cron,/var/log/pilot-*/fills the disk and reproduces this morning'sjbd2-hang fleet outage in ~5 days. Also captures the registryGOMEMLIMIT=48GiBdrop-in and the MOM responder topology.Docs-only; no code change.
