    Hi Paul,
    
    Thank you for the work. I downloaded the beta version, installed it and tested it. The SIGSTOPed process could pass the whole checkpoint procedure now. Congratulation! However, when I tried restarting the previously checkpointed SIGSTOPed process from its disk image, the RESTART procedure never completed. It blocks in cr_rstrt_req.c:cr_rstrt_child(). I guess, if you move the send_sig_info(SIGSTOP, NULL, task) stuff to cr_rstrt_task_complete(), the whole procedure will complete normally. Hope it helps.
    
    Best wishes!

    The first beta of BLCR 0.6.2 is now available at 
    http://mantis.lbl.gov/blcr-dist/
    Both source tarball and SRPM are available.  The filenames and MD5 
    checksums are:
      93249f20abd4eeec7a07db2f2a6cd2b2  blcr-0.6.2_b1.tar.gz
      e8ecba22c98de143ced20f83db76d8a1  blcr-0.6.2_b1-1.src.rpm
    
    This is a beta of a 0.6.2 patch release.  The intent of 0.6.2 is to fix
     
    a small number of significant bugs found in 0.6.0 and 0.6.1 and to add 
    support for 2.6.23 kernels and some vendor-patched 2.6.22 kernels.  A 
    NEWS entry summarizing these changes appears below.
    
    You are receiving this e-mail either because you are subscribed to the 
    checkpoint_at_lbl_dot_gov mailing list or because you have reported one of the
     
    bugs or previously unsupported kernel versions addressed by this 
    release.  I apologize if you receive multiple copies.
    
    I would greatly appreciate any feedback (positive or negative) 
    indicating if this beta fixes any problems you have reported with BLCR 
    0.6.0 and/or 0.6.1.  Only after I have sufficient positive feedback
     will 
    I make 0.6.2 available for download from the main BLCR web pages.

    0.6.2_b1
    --------
    December 17, 2007
    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).
     - Adds test cases for most of the bugs fixed in this release.
