I made some progress on that problem. Removing the io-threads xlator 
fixes the stability problem. It also greatly improves performances
while the server load decrease from 14 to 3 for the same operations.

It seems there have been some refactoring of xlatorx/io-threads since 3.1.
It does not use sem_timedwait() anymore, that was replaced by 
pthread_cond_timedwait(). 

Anyone has ideas here?
