For future runs: clean /tmp/xce_* between heavy ASAN test cycles.\n\n[UPDATE 2026-08-26, xce-test-rc-file task 1.1] Re-observed at much larger scale (14731 leftover /tmp/xce_* dirs, 653.6G, filesystem at 100% used / 0 available) and a MORE SEVERE manifestation than the original 'Expected Non-NULL' assertion failures: mkdtemp() failing inside test_repl_apply.c's make_test_persist_for_apply()/make_test_persist_in() hit ENOSPC, and that pre-existing test file's own hard exit(1) on mkdtemp failure silently killed the ENTIRE controller_unit_test process mid-run (right after test_repl_unit's last test, well before test_repl_apply's own output ever printed) -- exit code 1, no crash/ASAN report, no visible error in the redirected log until grepped for the literal 'mkdtemp failed' stderr line. A leftover orphaned controller_unit_test process (PID from an earlier invocation, blocked in futex_do_wait, presumably stalled retrying a WAL fsync against the full disk) was also found and killed. Fixed for this session via `find /tmp -maxdepth 1 -name 'xce_*' -exec rm -rf {} +` (630G reclaimed, 100% -> 29% used) -- confirmed no live xce process had any of those dirs open before deleting. General lesson: when controller_unit_test dies silently/instantly with exit code 1 and the log just stops mid-file with no crash signature, check `df -h /tmp` and grep for 'mkdtemp failed'/'calloc failed' before assuming a real regression -- this sandbox's /tmp accumulates leftover unit-test mkdtemp() fixture dirs across EVERY session indefinitely (no test file in this suite cleans up its own /tmp/xce_* dirs), so this will keep recurring until either the testsuite adds its own cleanup or something periodically clears /tmp.",
