Yeah, OOM killer going nuts on the system. Just how much mem was being used?
I had a 600mb swap on top of the normal memory, and on later tries even *that*
was eaten.
While doing make check, the machine locks up. Check the load avg!
# loadavg
1-minute: 24.180000 5-minute: 34.360000 15-minute: 32.110000
WTF x 10!!!
This is as far as it got:

That was the first machine, a Pentium II. The P4 is faster, with more memory,
200mb swap, but saw similar errors. Not as bad, but you could see it was same
type stuff.
silcd[18449]: segfault at 00000000 eip 0814b1e4 esp bfe93c4c error 4
Using sysrq due to the machine lock-up, I check the memory and 600mb of swap is
used, all of it! Plus the normal RAM. What is going on? Massive bugs in kernel
2.6.24.x? I rebooted 2.6.23.17, and will try 'make check' again.
Some time later ...
Now I run top and can see processes start eating memory, but why? httpd, sendmail,
they are not being used now, so why should GCC's 'make check' affect them? They
are 100% different programs from GCC!

Check cc1 above. Note the mem it's using all around. Insane. Similar behavior
testing under 2.6.23.17, and 2.6.24.4. The GCC was built with GCC-4.2.3, my
current compiler. None of this sort of thing happend before I started building
this GCC, so it really looks like something is either up with GCC 4.3.0 or its
interaction with something I have here. I know that building the java stuff and
testing it eats memory like mad, because I've always seen that building GCC. I
have the Pentium 2, with its 2gig swap, going now again. After the massive memory
usage with cc1 shown above, the testing and mem usage seem mostly normal for GCC,
so far. I'll let it run and see what happens. Killing cc1 off quickly restored
the memory to the system, BTW.
Now I am really afraid to install that. If it craps out, it's not like I can reload
anything off a distro disk because this isn't a distro, and you need a working compiler
to build a working compiler (the chicken & the egg dilemma).
Thoughts?
