INTERACTIVE UNIX System V/386 R3.2 V4 - tenox

Driver Fixes
• A problem in signal-intensive applications in which signals (typically
SIGALRM) could be lost forever has been fixed.
• A problem with some systems failing to reboot after shutting down the
system using "init 0" has been fixed.
• The following kernel tunable parameter limits have been raised:
NUMSP (number of STREAMS Pipes) to 256
NPROC (number of processes on the system) to 1000
MAXUP (number of processes for one UID) to 1000
MAXUMEM (the maximum size of a single user process) to 131072 (512 MB)

• The size limit on arguments to the exec system call has been made a
tunable parameter (ARG_MAX in mtune and stune). It has been tested
with the size limit set as high as 128,000 bytes.
• A problem probing memory size during boot on some machines, such as
Data General's 386 Dasher, has been fixed.
• Kernel profiling has been improved to work better with large kernels, or
kernels with many device drivers.
Kernel Driver Fixes
• The method used by a driver to determine whether a CD-ROM is High
Sierra or IS0-9660 format has been fixed.
• The ramd driver has been fixed to create the correct number of entries if
more then one RAM disk is configured. Node entries are now provided for
all RAM disk devices supported by the ramd driver.
