Diagnose FreeDOS HIMEM and EMM386 conflicts with a controlled boot menu that isolates XMS, EMS, UMB, ROM exclusions, and driver order.
Investigate Kubernetes OOMKilled containers with termination evidence, time-series memory data, runtime ceilings, node pressure, and load validation.
Configuring a RAM disk with the built-in RAM driver — a fast, volatile drive letter backed by memory, useful for temporary files and disk-heavy tasks.
Building a batch-file boot menu that manages memory-hungry TSRs — loading only what a chosen task needs, freeing conventional memory for everything else.
How to distinguish healthy ZFS ARC caching from real FreeBSD memory pressure, measure reclamation, and set a tested ARC ceiling safely.
Distinguish global, cgroup, cpuset and policy-driven OOM events; interpret victim scoring and build memory controls from forensic evidence.
Understand Linux page-cache reads, buffered writes, dirty throttling and durability boundaries without confusing write completion with stable storage.
Reading the memory pressure gauge correctly, telling normal swap usage from a real problem, and identifying which process is actually responsible.
Understanding what the Memory Compression process actually is before assuming it's a problem, versus identifying a genuine memory leak correctly.
Diagnosing whether high vmmem usage is a genuine leak or reclaimable page cache, and setting a deliberate .wslconfig memory ceiling that actually fits your workload.
WSL2's VM claims memory dynamically as Linux needs it and has historically been slow to release it back, plus what .wslconfig actually lets you control.
A source-backed guide to FreeDOS conventional memory, UMBs, the HMA, XMS and EMS, with safe Jemm and Himem configuration and troubleshooting practices.
