Error when sh start after chkfsys With QNX 6.2.1B


In our boot process we call a file from /etc/rc.d/rc.local. In
this sysinit file we do a chkfsys command before starting our process then
we get those errors:

sh: j_init: tcgetpgrp() failed: Inapropriate I/O control operation
sh: warning won’t have full job control

What we want to do is to start some process when the PC start, but if the
was not shutdown properly some files are corrupted this is why we want to
make a chkfsys before starting those process.

Thank you for any help
