If all you are doing is soft commits, your transaction logs are going to
grow out of control.

My recommendation:

1) Remove all commits from your indexing application.
2) Configure autoCommit with values similar to that wiki page.
3) Configure autoSoftCommit to happen often.

The autoCommit must have openSearcher set to false.  For autoSoftCommit,
include a maxTime between 1000 and 5000 (milliseconds) and leave maxDocs
