2. Bug Fixes¶
If the amount of free memory is low, OOM killer would kill the tasks from cgroups without memory guarantees first. However, it seems more reasonable to kill the tasks from cgroups which exceed their guarantees the most. (VSTOR-22575)
Processes could hang while closing a file located on the storage cluster. (VSTOR-23689)
