Package: dmtcp
Version: 1.2.4-1
Severity: normal
Setting --interval for the dmtcp_coordinator has no effect (same for env
var). This seems to be a new bug -- it used to work prior 1.2.4. What
happens is illustrated by the coordinator log below. Initially the
coordinator gets the correct checkpointing interval, but as soon as a
client connects it gets reset to zero. Afterwards it can be reenable via
dmtcp_command, and checkpoints will be created at the desired interval.
Consequently, repeated automated checkpointing in Condor also doesn't
work with 1.2.4 as the interval is only given to the coordinator once
upon start.
Here is the log:
