John, Thanks for the message. Page faults were very high. We did a major defrag last night, and ftp hasn't had any errors today. We started out with 83k+ blocks of less than 1000 sectors...72% of our free disk space was in these small blocks. After the defrag, we have 544 of these small blocks, only 1% of our free disk space. I didn't look at this until yesterday, because someone was supposed to have set this up as a weekly process on all of our systems several months ago....ooops.
