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. ** Attachment added: "kern.log from affected system" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842/+attachment/4933628/+files/kern_20170816.log ** Also affects: linux-aws (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1655842 Title: "Out of memory" errors after upgrade to 4.4.0-59 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
