My original thought is still the best idea I have.  I think that the 
other software on the system is heavily using the disk cache and not 
leaving enough of it for Solr's data.

 From what I can tell, the other software on the system is not using 
MMAP for disk access, so the large amount of disk cache usage is not 
reflected in the "Commit" number for those programs.

In the last screenshot, the Solr instances appear to be handling very 
little index data -- the Commit number is actually *smaller* than the 
Working Set number, which will not be the case when there is a lot of 
index data.  I'm betting that at the point when that screenshot was 
taken, all the index data had been deleted, possibly in preparation for 
rebuilding the indexes.
