A Runaway Build Dies Very Differently Under cgroup Than Under ulimit
Claude Code v2.1.233 added opt-in memory cgroup support for Bash tool commands on Linux. Capping virtual address space with ulimit -v and capping physical memory with a cgroup produce completely different failures — and only one of them lets your Node build start at all.
The 400-Character Preview That Was Still Holding On to a Megabyte
Truncating tool output in your own MCP server does not free the original. Node's sliced strings keep the parent alive. Here is the measured 13-character boundary, which flattening tricks actually work, and a heap-snapshot audit script that counts the retained parents for you.
When Memory Store Listings Returned Half the Rows: Migrating to agent-memory-2026-07-22
agent-memory-2026-07-22 changed memories.list: fixed ordering, stricter depth, segment-based path_prefix matching. How an audit quietly halved, an access layer that survives it, and measured depth=1 traversal cost.
Your Overnight Session Wakes Up at 3GB — Four Places Memory Piles Up, and How to Tell Them Apart
The Claude Code process I left running overnight had grown to 3.4GB of resident memory by morning. Here are the four accumulation sources closed in 2.1.209, how to separate what's left in your own setup by sampling RSS slope, and a watchdog pattern that folds a session before it hurts.
Will It Stay Light When You Run It Unattended? Observing and Capping Claude Code's Long-Session Memory
How to keep long, unattended Claude Code sessions from slowly getting heavier — with a tiny ps-based RSS sampler, a rolling-baseline watchdog, and session segmentation, shown with working scripts and a before/after comparison.
