          I root caused this MB to an issue with timers + rebalance out of an eventing node. The issue existed for some time now and got exposed in system longevity. We have a fix under Review & CI which should fix the problem.

          Another thing we noticed is, when the eventing node is going out of the cluster, bucket ops through libcouchbase seem to slow down significantly. This part needs more investigation. Nonetheless, the patch should fix the problem of rebalance getting stuck
