This is on one of my bare metal machines, first iteration:

min_free_kbytes.c:91: TINFO: Setting /proc/sys/vm/overcommit_memory to 2
min_free_kbytes.c:95: TINFO: Setting /proc/sys/vm/min_free_kbytes to 67584
min_free_kbytes.c:111: TBROK: fork: ENOMEM (12)
tst_test.c:1933: TINFO: Killed the leftover descendant processes

Kind regards,
Petr
