Hi all, I get the following error messege during my cross-node checkpoint/restart test: --------------------------------------------------------------------------- Checkpoint command: cr_checkpoint -f context_4644030.2 --run 10983 ioctl(/proc/checkpoint/ctrl, CR_OP_CHKPT_REQ): Operation not permitted --------------------------------------------------------------------------- the status value returned by this operation is 1 ranther than 0 This error appears randomly on some nodes for some jobs, but the same checkpoint operation of other jobs which are exactly of same codes works fine. Can anyone explain this error? --Yuan Yuan Wan -- Unix Section Information Services Infrastructure Division University of Edinburgh tel: 0131 650 4985 email: [email protected] 2012 Computing Services, JCMB The King's Buildings, Edinburgh, EH9 3JZ
