The trail I'm seeing say something more wrong with the machine than cyrus.
The machine is not doing ANY I/O or is so busy doing some other I/O it
stops doing anything useful. Not running XFS filesystem per chance are you?
If the machine were OK it would bog down under nasty load, but it wouldn't'
STOP DEAD like that. You need to look around poke at things, try to find
whats broken causing it to stop dead like that, and it's probably not
Cyrus. It could be if it's going amok, but I really doubt it.
Linux has a LOT of known problems with huge amounts of memory...try
reducing your memsize to 3Gb or 4Gb either by physically pulling chips or
memsize=<blah> on the boot line Lilo you can say something like 'linux
memsize=4096M' in GRUB you have to use 'e' to edit one of the options, then
scroll down to the line containing kernel.... and add memsize= to the end
of it by 'e' editing that line, then you can use b to boot. See if that
helps your performance. There is a reason, I'm just REALLY doubting it's
actually Cyrus at the heart of this one.
