Is this a known bug?

[Huang, Eric]

Hi Folks,

 

I encountered a problem during IOzone throughput tests with 4 threads.
The file size is 2GB (my system has 2GB memory). The iozone process will
hang there in a state of "uniterruptable wait" during the "random write"
test, and eventually the whole system stops responding. On the server
side, I noticed one error message saying can not map the user ID of
"nobody". 

 

I wonder why, since the rest of the tests finished fine, and a test of
256MB file-size also went OK.

 

Thanks a lot.

 

Eric
