:>     Ugh.  Do me a favor.  Do a 'sysctl vfs.hammer' every few seconds while
:>     you are copying and cut and paste the last few as of when it crashes.
:>     That will tell me which structure is blowing out the memory.
:
:Here it is. Each --- marks a one second pause.
:
:vfs.hammer.count_records: 601674
:vfs.hammer.limit_recs: 320000
:vfs.hammer.limit_irecs: 102400

     Yow. 600,000+ records cached in memory.  Reducing the irecs limit
     should fix the problem.  Try changing it to 20000.
