One thing that comes to mind is that you can smarthost your outgoing

Hi All,
I am getting the following array while trying to compile uipc_syscalls.c
file.
/vobs/atm/netbsd/sys/sys/syscallargs.h", line 30: zero or negative
subscript
This is because the code in syscallargs.h is defining an array of size
0.
The code that is creating problem is
#define syscallarg(x)
:If this is a result of the shared memory, then my sysctl should fix it.

:Be aware, that it doesn't fix it on the fly! You must drop and recreate
:the shared memory segments.

:better to reboot actually and set the variable before any shm is
