REVIEW: https://review.gluster.org/17332 (rpc: log more about socket disconnects) posted (#1) for review on release-3.8 by Milind Changire (mchangir)
Description of problem: One of the common problems we encounter are frequent connects/disconnects. Frequent disconnects can be either: 1. voluntary where the process calls a shutdown (2)/close (2) on an otherwise healthy socket connection. 2. involuntary where we get a POLLERR event from network. While debugging this class of issues, it would help if can identify whether a particular disconnect falls into which of the two above categories. We need to add enough log messages to help us classify.
This bug is getting closed because the 3.8 version is marked End-Of-Life. There will be no further updates to this version. Please open a new bug against a version that still receives bugfixes if you are still facing this issue in a more current release.
