Comment 95 for bug 1655842

We are also experiencing this issue running linux-aws 4.4.0-1028.37, which tracks Ubuntu kernel 4.4.0-89.112. Our use case is very similar to comment #86 (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842/comments/86). In our case ElasticSearch 2.4.5 is running under Java 1.8.0_131 with a ~29GB heap; we downsized from 31GB as a troubleshooting effort with no change to the frequency of OOM. The issue also occurs regardless of vm.overcommit_memory being set to 0, 1 or 2.

The relevant data from kern.log (with redacted hostname) is attached; I'm happy to provide additional logs or test different kernels, but since our use case is i3-class instances in AWS, we need the nvme enhancements and enhanced network I/O provided by the linux-aws package.
