Dear DMTCP team -- First of all, it *awesome* to have this available and
use it with Grid Engine to allow timed-out jobs to be continued!
I want to report two issues I have seen with Java jobs of this form:
gunzip -c foo.gz | java blah blah 2> blah.err | gzip > bar.gz
1) Typically fails in restart if restarted on a host different from that
used for first part of the run. The complaint is about Unix shared-memory
stuff in the Java process.
Workaround: Restart only on the original host.
2) In the 2> redirection, if I give an absolute path name, it works, but if
I give a relative pathname (e.g., a name in the current directory), it
fails in the Java process during restart. I saw an OPEN MPI bug that was
fixed concerning stderr -- wonder if this the same / related?
Workaround: give a full absolute pathname.
I am using version 2.3.1, built from the sources.
Regards -- Eliot Moss
