cannot rebuild kernel

Marcos_9 — Tue, 09 Jul 2002 09:41:04 GMT

Im getting this error when I try to pass some kernel patches, even when I try to change parameters through SAM. The error I get is
# mk_kernel -s system
Generating module: krm...
Compiling conf.c...
Loading the kernel...
Out of memory.
*** Error exit code 12
I cannot change any parameters to change maxdsiz or any other.
Any idea??

Thanks in advance

Hi

look at ulimit -a

then maxdsiz via sam

If ulimit very low then

Change maxdsiz in the kernel,

run the following command as root
:

echo "maxdsiz?W 0d16390" | adb -w /stand/vmunix /dev/kmem

Rebooted and it will be possible to generate a kernel without getting the "Out of Memory" error.

cp /stand/vmunix to other name if possible first to be safe

you may have to use adb
just do following and reboot the machine. Be sure to copy the vmunix if in case required.

# adb -w /stand/vmunix
maxdsiz?2D <- input this
maxdsiz:
maxdsiz: 4096 16384
maxdsiz?W 0d16390 <- input this
maxdsiz: 61EC28 = 4096
control-d <- input this

Hi Marcos:

Verify that you are not deficient in swap space. Insufficient swap space is another reason for "out of memory" errors.

# swapinfo -tam

Thak you everybody
It has been solved right now with the help of all of you. It was a problem with the kernel. Just made things as proposed by Steve and Amil and everything is working fine now.

Thanks for your time
