| Issue | Symptom | Workaround | |-------|---------|-------------| | Graphics flickering | When rotating a model with >5,000 primitives, lines disappear. | Disable "Dynamic hidden line removal" in Settings → Graphics. Or set D3D_EMULATION=1 in evars.bat. | | Database "DBERR" | Session crashes with "Database error on write - record locked". | Increase DB latch timeout in MONITOR module. Use SYSTEM/UNLOCK ALL (admin only). | | PML memory leak | After 4-5 hours, UI becomes slow. | Restart PDMS. Schedule daily restarts for designers. Apply a memory-cleaning PML snippet (pml rehash all). | | License checkout failure | "No license for module DRAFT" despite available seats. | Reboot license server.
