So, AFAIU, you got 124 since timeout(1) exited with that status (and killed all parallel(1) executions (after 2 minutes in that case?)... ... and when you set NOTMUCH_TEST_TIMEOUT=0 then timeout(1) was not executed and a test hung (probably T355-smime). In any way you get it again to hung state (w/o using timeout(1) to mess around) you probably can peek things with ps, /proc, strace, gdb, or with some other (potentially more sophisticated ;) tools. > > d Tomi
