I have a rebalance that has failed on one peer twice now. Rebalance logs below (directories anonomised and some irrelevant log lines cut). It looks like it loses connection to the brick, but immediately stops the rebalance on that peer instead of waiting for reconnection - which happens a second or so later.
Is this normal behaviour? So far it has been the same server and the same (remote) brick. </font></pre><pre id="gmail-hterm:copy-to-clipboard-source" style="user-select: text; top: -99px;"><font color="#000000">
The brick shows a high number of disconnects compared to the other bricks on the same server</font></pre><pre id="gmail-hterm:copy-to-clipboard-source" style="user-select: text; top: -99px;"><font color="#000000">
./export-md0-brick.log.1 2
./export-md1-brick.log.1 2
./export-md2-brick.log.1 181
./export-md3-brick.log.1 2 </font></pre><pre id="gmail-hterm:copy-to-clipboard-source" style="user-select: text; top: -99px;"><font color="#000000">
Any clues? What could be causing this because there is nothing in the log to indicate cause.</font></pre><pre id="gmail-hterm:copy-to-clipboard-source" style="user-select: text; top: -99px;"><font color="#000000">
