Performance tunables in [1] are normally recommended for qemu - 
libgfapi. The last two options are related to quorum and the remaining 
tunables are related to performance. It might be worth a check to see if 
these options help provide better performance.

Do you happen to know if self-healing was in progress when the machines 
stall?
