Well, that requires to crash a mail server in busy hours on purpose. I will collect if it happens again by accident. > Does it unstick, or does it remain stuck forever? That is, what makes > you conclude `everything behaves like if all I/O were serialized'? It seems processes get to execute after a long time, since the load manages to go up and down. I did not conclude about serialized I/O, I just said it behaved somehow like it: all processes doint I/O wait in tstile and sometime get an opportunity to work. But it could also be that there are very small windows for all processes to run. -- Emmanuel Dreyfus http://hcpnet.free.fr/pubz [email protected]
