That's not a crash.
That's watchdog timeout indicative of lustre spending too much time
waiting on io.
As such you need to somehow decrease the load on the system (by e.g.  
reducing
the number of io threads - was discussed on this list recently),  
increase obd_timeout or
get faster disk subsystem.
