Hello,
I am using DMTCP to try and checkpoint a simple Java program, source
of which can be found at http://pastie.org/10801783.
In the program input.txt is a large file which contains several lines
which I am trying to print. I am checkpointing the program by sending
the signal to checkpoint externally through the dmtcp_coordinator.
Although, I expected the checkpointing process to work with the open
file descriptor, it appears that dmtcp is unable to checkpoint the
program properly, and results in some error messages like:
[43000] NOTE at timerlist.cpp:107 in removeStaleClockIds;
REASON='Removing stale clock'
staleClockIds[i] = -100842
[40000] WARNING at kernelbufferdrainer.cpp:125 in onTimeoutInterval;
REASON='JWARNING(false) failed'
_dataSockets[i]->socket().sockfd() = 11
buffer.size() = 140
WARN_INTERVAL_SEC = 10
Message: Still draining socket... perhaps remote host is not running
under DMTCP?
[40000] WARNING at kernelbufferdrainer.cpp:125 in onTimeoutInterval;
REASON='JWARNING(false) failed'
_dataSockets[i]->socket().sockfd() = 11
buffer.size() = 140
WARN_INTERVAL_SEC = 10
Message: Still draining socket... perhaps remote host is not running
under DMTCP?
In case it matters, I am using Ubuntu 15.10 with 4.3.0-040300-generic kernel.
I am also using the latest dmtcp source code available in Ubuntu repository.
Could anyone please let me know why this happens and whether there is
a way to get it working?
Thanks,
Pratyush Patel
