- **AIM "connection broken" recurrence under host memory pressure.** SQLEXPRESS has no `max server memory` cap; under pressure Windows trims working sets and reaps idle Telerik pool slots, causing user-facing `Telerik.OpenAccess` connection-broken errors. First seen 2026-05-05 (Station 1), recurred 2026-05-06 ~12:14 PM (Station 1 again). Recommended fix: cap `max server memory` on SQLEXPRESS (~12-14 GB), WID (~512 MB), and AIMSQL (~256 MB). Long-term: dedicated DB host or Server 2019 migration. Note: misleading instance name burned ~1 day of triage — do NOT stop SQLEXPRESS thinking it's idle.

| 2026-05-06 | Howard | AIM connection-broken recurrence (Station 1, ~12:14 PM). Re-enumerated all 3 SQL instances on IMC1; corrected wrong-instance diagnosis from 2026-05-05 (production AIM is on `IMC1\SQLEXPRESS` Standard, not `IMC1\AIMSQL` Express). Confirmed AIMSQL is orphan (zero active clients, 2023-era DBs only). Unregistered the daily 02:30 AIMSQL restart task (it was restarting the wrong instance). Audit artifacts left on disk at `C:\Windows\Temp\aimsql-restart.{ps1,log}`. No service touches. | DIAGNOSED |

Ticket #32218 invoiced, 1.5 hrs from prepay (14.0 → 12.5). Confirmed `ServerIMC` (192.168.0.63) is a real authentication-degrading phantom DC (SRV/A claim DC, LDAP/Kerberos refuse). | DEPLOYED |
