Hmm... looks very interesting looks like you have ~1.8 GB (assuming page size
is equal to 4k). The log shows that OOM occurred several times.
Kamalesh, how much memory do you have the on the system and what test were
you running when you hit this problem? Is the problem reproducible? What is
the configured swap size?
