Hi Bart,<br>
<br>
I can't get those specific commands to cause a problem for me (using trunk at least, I haven't tried 2.7.1 yet). However, I definitely see some problems in LTP. For me it eventually hangs on the rename06 test, but valgrind is complaining about some memory problems in the pvfs2-client-core symlink path as well before reaching that point.<br>
<br>
I'll look into it and let you know what turns up.<br>
<br>
I might also see if I can cook up a script to include LTP in our nightly tinderbox builds as well; there are some good tests in here.<br>

Hello all,<br>
<br>
I have run into a few problems when running some tests against the 2.7.1 release on RHEL4. They all seem to hinge around large file names of 256 characters or greater. The commands fail gracefully - reporting an error that the file names are too long - but the next access of PVFS (an 'ls' for instance) hangs the system so that it has to be rebooted. I ran into them using the LTP test suite, but they can be reliably repeated with simple commands. Create, open, rename, and stat are the operations that fail, and some example commands are provided below. The file does not need to exist for the open or stat commands. Occasionally it takes a few seconds after command has been executed for the problem to show itself. Do these commands cause problems for anyone else, or is it something unique to my setup or environment?<br>
