Description hjl 2001-07-12 15:10:27 UTC
When I rebuild glibc 2.2.3-13 rpm, I get

VM: killing process makeinfo
VM: killing process ld.so
VM: killing process syslogd
VM: killing process cc1

under 2.4.6-1. I have no problem with 2.4.5-10. It
happens on 2 machines:

# free
                total       used       free     shared    buffers    
cached
Mem:         93172      89816       3356          0      58348       9980

Swap:       530104      10872     519232

I don't think memory is a problem.

I got the same problem with 2.4.6-2.  When I built glibc 2.2 with
parallel make, I got

VM: killing process ld
VM: killing process ld
VM: killing process ld
VM: killing process ld
VM: killing process ld
VM: killing process makeinfo
VM: killing process makeinfo
VM: killing process ld
VM: killing process ld
VM: killing process ld
VM: killing process ld

It is on a machine with 256MB RAM and 512 MB swap. When it happened, about 40 MB
swap
was used and load average was about 8. I had no problem with 2.4.5-10.

A glibc Makefile to trigger the VM bug.

Comment 3 hjl 2001-07-22 18:12:58 UTC
I uploaded a Makefile for glibc which triggers
the VM bug. It happens to me on UP machines with
96MB and 256MB RAM.

Comment 4 Jay Turner 2002-03-19 02:31:07 UTC
Can I close this issue out?  VM problems are lots better in the latest kernels
aren't they.

Comment 5 hjl 2002-03-19 04:47:05 UTC
Please close it. It works fine now.
