The shell hangs as you described on "make world" when the PID
hits 32768. Looks like this was the old limit and things changed
around release 3.
I went to recompile the kernel with "define PID_MAX 30000" in
/usr/src/sys/sys/proc.h and got a new build error that I'm still
trying to resolve:
In file included from /usr/src/sys/sys/buf.h:258,
from /usr/src/sys/i386/i386/genassym.c:47:
/usr/src/sys/sys/proc.h:670: error: expected '=', ',', ';',
'asm' or '__attribute__' before 'PID_MAX'
/usr/src/sys/sys/proc.h:769: warning data definition has no
type or storage class
/usr/src/sys/sys/proc.h:769: warning: type defaults to 'int'
in declaration of 'pidhashtbl'
*** Error code 1
Line 670 in proc.h is the define PID_MAX line. I have the
feeling I may be missing something obvious here, but I haven't
been able to sort out the problem.
