That user should have been running Office 2010.

I installed v1.8.3 and ran it without the above change and it consumed all available memory and locked up Windows as I expected. I modified the "case.prefs" file and added the "UseExperimentalPstCrawler=True". I ran the problematic PST file again and it Finished Processing. I hope this helps determine where the problem lies. I've processed a lot of PST files in the last few years and this is the first problem I've encountered. Do I need to add this line every time? I'll be moving some processing to Intella Connect very soon. Will this be an issue there?

I will try this in 1.8.3. I had noticed that AdamS above seemed to have the same problem with memory consumption on 1.8.3.

I've also encountered a similar situation this week and I'm using Intella Professional 1.7.2-r26532. Processing gets to the recovery of deleted items and memory usage has stayed within 1GB of when I started the processing. Then, within a 5 second timeframe, memory usage consumes the maximum available (12GB on this PC), the disk activity light is solid and Windows appears to freeze. I think it is attempting to roll out chunks of memory to disk. I've narrowed it down to a single .OST file (1.1GB). I initially suspected that the file was corrupt and ran SCANPST on it until it gave me no more errors. I re-processed the file with the same result. Here is what I find in the main-2015-03-03.log file around the time that memory consumption seems to skyrocket: [iNFO ] 2015-03-03 11:52:07,305 [AWT-EventQueue-0] Logback logging API implementation is configured.
