I kicked off a defrag on our 50gig last night and it ended up hanging at 56% for about an hour and a half. I checked the I/O Reads and Writes on eseutil process and it wasn't updating. I hit ctrl-con the eseutil screen and the util immediately updated to 58%. Roughly 5 mins later the I/O reads and Writes stopped updating again, hit ctrl-c and up to 60%.
I'm currently watching it go through the rest of the process, and will hit ctrl-c at each lockup but does anyone know what would be causing this?

And yes, I created a backup of the database before running the defrag.

This is, from what I've read, not a "good thing".... I'd post a query to the alt.microsoft.exchange.admin newsgroup ASAP. There are tone of MVPs hanging out there. I'm guessing that you just didn't wait long enough. a 50GB datastore will take a *long* time to run. It will surely take at least several hours. I hope you have enough free space. You need at least 110% of the datastore size in freespace...

Hank is right. ESEUTIL takes a long, long time to chug through 50 GB. Most estimates have ESEUTIL processing only about 4 GB to 6 GB per hour. It's not at all uncommon for the progress indicator to freeze at some number for hours on end, only to jump by tens, then hang again for an hour. Last time I ran ESEUTIL against my company's (then) 40-something-GB IS, it took over six hours. Hang in there!
