Thanks to all who responded. Things are running well! The IBM version of the JRE for Intel 64 seems to run good, and the stalling issue has dissappeared. (when the solr instance stops responding and freezes up)
What I learned is that solr is a great product but needs "tuning" to fit the usage. Changing some config settings can make the difference between a usable and unusable system. I guess for most smaller indeces things will run fine out of the box, but if you have a large index then you have to play around a bit -Alex ------------------------------------------------------------------------------------------------ >Install the AMD64 version.

I was confused by the naming convention. Seems to work fine now, well, I mean fine that it can be started with a larger heap. We'll see how it runs overnight Thanks again, Alex
