It has been worked around in Nagios 2.0. Now you can instead specify 
'hostgroups' in the host object definition, and you can specify 
wildcards for hosts (only * so far though).

The reason it is 8192 is that
a) it is a multiple of 4096, which is the default blocksize on ext[23] 
file systems.
b) it's a nice ballpark figure that's reasonably set and doesn't hog a 
lot of memory during startup. For most users, this is quite enough.

If it should be raised to anything, it should be to a multiple of 4096.
