High load after upgrading from 5.2-RC2 to 5.2-Release

High load after upgrading from 5.2-RC2 to 5.2-Release

Hey there,

I've upgraded from FreeBSD 5.2-RC2 to 5.2-Release last Friday and I'm
having a very strange problem since. I've noticed that all of a sudden
all the services my FreeBSD Box is offering were very slow, so I had a
look at it and discovered that the avg. load on my Server was about
After meandering around for quite some time I've discovered that some
weird process is eating up more than 50% of my CPU, here is an output
from top (top -s1 -I -S):

27 root -48 -167 0K 12K WAIT 27:42 59.08% 59.08% swi8: tty:sio clock

The 59.08% is the CPU load. Now does anybody know what eaxctly this
swi8: tty:sio clock is for? I've found any useful information. Btw:
also after rebuilding with RELENG_5_2 the problem didn't disappear,
however if I reboot into single user mode the problem seems to
disappear (load avg 0.xxx). Under [1] you can find a graph with the
current load. Thank you very much for any tips or hints!

1. Looking for AIX 5.2 binaries, IS anyone running Ruby on AIX 5.2 ??

2. JPEGs load slowly or won't load at all on some websites in Internet Explorer 5.2

On certain websites, like Amazon and Mapquest, jpegs either load very
slowly or don't load at all. I don't think the issue is my computer
hardware(1 GHz PowerPC G4 with 768 MB RAM). Doesn't seem to be
connection speed, either. I can access these sites in OS 9 or in
Windows through the same DSL connection without this problem occuring
at all. Are there any known issues with OS X in this regard? Seems to
me like OS X has trouble playing nicely with web browser. Any help is
greatly appreciated. Thanks.
