Re: [Gluster-devel] 1.3.0pre2

[Anand Avati]

Brent,
  first off, thank you for trying glusterfs. Can you give a few more
  details -
  
  * is the log from server or client?
  * the log message from the other one as well.
  * if possible a backtrace from the core of the one which died.
  
  can you also tell what was the I/O pattern which made the crash? was
  it heavy I/O on a single file? creation of a lot of files? metadata
  operations? and is it possible to reproduce it consistantly with some
  steps??
  
  Also we recently uploaded pre2-1 release tarball. That had a couple of
  bug fixes, but I need to get your answers to say if the fixes apply
  to you as well.
  
  Please attach your spec files as well.
  
  regards,
  avati
