Hmmm....Something is certainly wrong. 11 writes at 137k - 275k seconds (which is where your 1.5M seconds sum is coming from) is bogus.
What version of Solaris is this ('uname -a' and 'cat /etc/release')?
Your running this on an NFS server, right (not client)?
Is this a benchmark? I ask because the file names (file1, file2, etc)
seem like names used in synthetic benchmarks.
I need to take a closer look at the code and figure out how to chase
this. Either there's a bug somewhere, or we're missing something.
Thanks,
