What is your commit strategy? A hard commit (openSearcher=true or false doesn't matter) should close the current tlog file, open a new one and delete old ones. That said, there will be enough tlog files kept around to hold at least 100 documents. So if you're committing too often (say after every document or something), you can expect to have a bunch around. The real question is whether they stay around forever or not. If you index more documents, do old ones disappear?
Here's a writerup: http://searchhub.org/2013/08/23/understanding-transaction-logs-softcommit-and-commit-in-sorlcloud/ If that doesn't help, what version of Solr? How big are you tlog files? Details matter.
