Sean-san,

Now tiger503 encountered suspicious hangup again.

As you said, perhaps the cause of the problem derives from the hardware
or memory chip issue.

Could you replace the memory chip of tiger503 from 8 x 512MB to 4 x 1GB?
Tiger503 worked fine original 4 x 512MB memory, so, perhaps it is good
for stability.

Currently, tiger503 serves as "live20.2ch.net". It is one of busist
server in 2ch. Tiger503 serves about 200,000-250,000 posts every day.
So, I want to complete our project.

Regards,
