Re: GC [ParNew...] took 299 secs causing region server to die

We never did pinpoint the underlying causes but we found a way to resolve
this issue -- by upgrading ubuntu from 9.04 to 9.10.  The surmise from our
SysAdmin was that there was some incompatibility between the new hardware
and the old drivers.  So it's most definitely out with the old and in with
the new.
