But quickly scanning the sourcecode, I still cannot find the source of the problem. And one question arising: w@Amnesiac:~$ kdump| grep -c NAMI 11 w@Amnesiac:~$ ktrace -t n ls /testmount >/dev/null 2>/dev/null w@Amnesiac:~$ kdump| grep -c NAMI 18 Where from this change of calls to NAMI stems? The second output has follwing lines more (at the end of execution): 1750 ls NAMI "/etc/malloc.conf" 1750 ls NAMI "/testmount" 1750 ls NAMI "." 1750 ls NAMI "/testmount" 1750 ls NAMI "/testmount" 1750 ls NAMI "/testmount" 1750 ls NAMI "/testmount" Cheers, Wiktor Niesiobedzki
