> could you convert "large number" and "high load" into decimal numbers?

Learning more as I go here. Installed Cache Manager. See below.
When it was last started it was completely recompiled and all cache
files deleted. Am I going to have a problem with file descriptors?
Looking at top it appears virtually all the RAM is used up. There is
1G of DDR2 of which top says 6M is free and its a single SATA drive.

Thanks.
