That isn't very many. Your root filesystem probably has
more. File count is not the problem.

Upgrade. Lots of fixes between 2.5.4 and 2.5.6. Correction
to above: Data volume could be pushing you over the edge
in 2.5.4.

Should be plenty of memory, especially with only 100,000
files. And the worst of the swap storms were fixed in
2.4.18

No.
The most likely culprit is the fact that you are down-rev.
Get up to 2.5.6 and if the problem persists we'll revisit
it.
If the problem persists you should characterize file sizes
and identify the largest file size.
