We had installed the mainline kernel on two machines and tested it again. The issue still remains. One of the two machines get slow, lost the drdb connection en begin to hang.
The other machine works fine (just like before). ** Attachment added: "drdb status.png" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1629260/+attachment/4755072/+files/drdb%20status.png -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1629260 Title: drdb kernal 4 crash Status in linux package in Ubuntu: Incomplete Bug description: After upgrading ubuntu 14.04 LTS from kernal 3 to kernal 4.4.0-38-generic, we got issues with DRBD. Especially during high load, the drdb kernal will gif issues. The DRBD status go's to a timeout and the server becomes unstable (also the KVM's running on it) and afther some minutes/hours, the system hangs. Only a hard reset is possible. This problem randomly appear after a few minutes / hours / days. Got this issue on multiple servers. The workaround is to go back to the old kernel.
