Hi Alan,
Thanks for making us aware of this problem. We weren't aware of it.
We're committed to providing you with a prompt solution to this (in the
next few days). If you don't mind, we'd like to simply send you a tarball,
so that you can verify within your own working environment that this
fixes the problem.
DMTCP 1.2.7 was released in March of this year. I'm assuming that
the older DMTCP 1.2.6 used to work with Condor. We are planning to shortly
issue DMTCP 1.2.8, and we can add any needed fixes into DMTCP 1.2.8.
The tarball we send to you will be based on the upcoming DMTCP 1.2.8.
Kapil,
You had originally written the DMTCP_RESTART_DIR capability --
in part to support Condor. Could you look at any changes that may
have affected it between 1.2.6 and 1.2.7?
