More than 100 files in the Log Server cache directory

Hello!

Got "More than 100 files in the Log Server cache directory" alert in my console!
Don't know what to do with it. Nothing helps.
Tricks from below KB's articles doesn't help:

1. http://www.websense.com/content/support/library/web/v77/triton_web_help/ts_ls_cachefiles.aspx

2.http://www.websense.com/support/article/t-kbarticle/BCP-files-are-not-written-to-the-SQL-database

Well... actions from articles helps, but only for 10 minutes and then alert appears again.
My SQL version is: SQL server 2008 R2

Any suggestions?

Thanks in advance!
