I received these in my debug output during a run that failed: [2010-06-30 12:34:25] D [read-ahead.c:468:ra_readv] readahead: unexpected offset (8192 != 1062) resetting [2010-06-30 12:34:25] D [read-ahead.c:468:ra_readv] readahead: unexpected offset (8192 != 1062) resetting [2010-06-30 12:34:25] D [read-ahead.c:468:ra_readv] readahead: unexpected offset (8192 != 1062) resetting [2010-06-30 12:34:25] D [read-ahead.c:468:ra_readv] readahead: unexpected offset (8192 != 1062) resetting I disabled the read-ahead translator as well as the three other performance translators commented out in my vol file (I'm on GigE; the docs say I can still reach link max anyway) and my processes appear to be running smoothly. I'll go ahead and submit the bug report with tracing enabled as well. -Brian -- Brian Smith Senior Systems Administrator IT Research Computing, University of South Florida 4202 E.
