One easy thing to do is run "crash" and type "strstat" to get streams 
statistics, and look for failures and/or maximums near the limits (you do 
not always get any sort of notification of failures - just unusual 
behavior).  If you find anything, then up those streams parameters and 
rebuild your kernel.
