To fix problems found in 0.6.1, I am releasing BLCR 0.6.2. It can be found at the BLCR Downloads page: http://ftg.lbl.gov/CheckpointRestart/CheckpointDownloads.shtml From the NEWS file: 0.6.2 -------- January 14, 2008 Bug-fix and expanded-support release. - This release adds support for 2.6.23 kernels. - This release adds support for SuSE's 2.6.22.x kernels. - This release fixes a file descriptor leak that occurred on restart from a checkpoint-of-self requested via cr_request_checkpoint(). - This release fixes a deadlock (and unkillable process(es)) when a multi-threaded process aborts (or omits itself from) a checkpoint under certain conditions. - This release fixes a restart-time failure when a checkpoint includes a pipe with one end outside the checkpoint scope, and data is buffered in the pipe. - This release fixes a bug with the cr_request{,_file}() calls in which a failed checkpoint would cause failure of the next one if it had the same destination file name. - This release fixes a race condition with the cr_enter_cs() and checkpoints in multi-threaded processes. - This release fixes post-checkpoint signal delivery (--stop and friends) to occur after the checkpoint is fully completed. See bug 2201 for a full description of the problems addressed by these changes. - This release documents (and fully implements) signal-delivery options to cr_restart (see bug 2200). - This release fixes two kernel Oopses (bugs 2222 and 2223) due to races against processes/threads that are exiting. - Adds test cases for most of the bugs fixed in this release. - Minor improvements/changes to documentation - Other minor bug fixes -Paul PS You are receiving this either because you are on the checkpoint_at_lbl_dot_gov list, or because you've recently sent email to the list (or me directly) asking about BLCR status. -- Paul H.
