Hmmm, perhaps my description is too vague to attract a response.
Let's start with this. How can I manually test if checkpointing is
working? I'd like to test checkpointing a job on a FC3 node and
restarting it on a RH7.3 node. Again, I am using condor 6.7.7
installed from rpms.

First let my start off by saying that I have been a very happy
condor user for over a year now. However, a few of our machines
got upgraded to Fedora Core 3 and all hell has broken loose on our
condor install. Now, I am a frustrated condor user who is
desperately trying to be happy again. :-)
I am having problems with condor version 6.7.7 and standard
universe jobs exiting with signal 11 after restarting from a
checkpoint. Every time the problem occurs I see something like the
following in the shadow log:
6/2 17:26:37 (10.5) (312):Read: Done restoring file state
6/2 17:26:37 (10.5) (312):Read: About to restore signal state
6/2 17:26:37 (10.5) (312):Read: About to return to user code
6/2 17:26:37 (10.5) (312):Shadow: Job 10.5 exited, termsig = 11,
coredump = 0, retcode = 0
6/2 17:26:37 (10.5) (312):Shadow: was killed by signal 11.
Specifically the problem only occurs when a job running on a Fedora
Core 3 node gets checkpointed and restarted on one of our Redhat
Linux 7.3 nodes (and possibly vice versa).
Some info about our setup:
-Negotiator/Collector is running Redhat Enterprise Linux AS release
3 and is not a member of the pool (not running condor_startd)
-compute nodes are either running Redhat Linux 7.3 or Fedora Core
(1 and 3)
-all nodes were installed using the 6.7.7 dynamic lib rpm's
(glibc22 or glibc23 where appropriate)
-USER_JOB_WRAPPER is NOT set
I had previously been using condor version 6.6.9 with the
USER_JOB_WRAPPER variable set as mentioned in order to workaround
the 2.6 kernel exec_shield problem. However, I would still see the
same symptoms (termsig = 11 on checkpoint restart).
In order to test if checkpointing works from the command line I
tried the following:
fedora_node> setarch i386 ./myapp
fedora_node> kill -TSTP <myapp_pid>
RHL_7_3_node> ./myapp -_condor_restart myapp.ckpt
And the app segfaulted.
Any help would be greatly appreciated!
