The Usage card showed runtime.MemStats.Sys, a never-shrinking high-water mark of reserved address space that also counts memory already returned to the OS, so it overstated real usage (e.g. ~300 MB on an idle 1-client server). Report process RSS instead so the number matches the OS and drops as memory is freed. Replace the auto GOMEMLIMIT that targeted ~90 percent of total system RAM (a near no-op while the heap sits far below the limit, and a GC-thrash risk on small/shared VPS per go.dev/doc/gc-guide) with: a lower default GOGC (XUI_GOGC, default 75), a periodic debug.FreeOSMemory job (XUI_MEMORY_RELEASE_INTERVAL, default 10m, 0 disables), and a soft limit applied only from an explicit budget (GOMEMLIMIT, XUI_MEMORY_LIMIT, or a real cgroup cap at 90 percent).
