Subject cluster machines dying
Date Fri, 26 Dec 2008 19:41:45 GMT

I am experiencing a strange problem with hadoop-0.19. I have set up  
cluster with 4 machines. These are older machines, which have been under
heavy use for years. Once I have started to run hadoop on them they
unexplainably die after approximately 24 hours of use.

I have not even run any tasks on they yet. They are now accumulating  
some data
files, being copied in DFS. There is nothing in syslog prior to the  

Memory usage is moderate (no swap is used). CPU load is under 1. Does  
anybody seen
something like this? What steps I could take to diagnose this problem
