@aahmed-se @pkumar-singh @srkukarni @dlg99 It seems that this PR was never merged. Was that intentional?

We are also facing the grpc deadlock issue described in PR #8351 (that PR had to be reverted at that time because of multiple issues described in the comment history) and it would be important to get the problem fixed asap.

@aahmed-se Were there some obstacles in upgrading grpc to 1.31.0 ?

[aahmed-se]

THis requires some changes in bookkeeper first and the reference version in pulsar be upgraded.

[lhotari]

@aahmed-se Thanks for explaining. Would you mind adding a reference to the changes that are required? What is the status of those changes?

[aahmed-se]

The changes have been made internally in our bookkeeper they are quite substantial.
I don't know the current plans on when they can pushed upstream. It depends on when there is downtime in work.

@diegosalvi @aluccaroni which GRPC version do you have in EmailSuccess stack ? IIRC we had upgraded to latest version recently

[diegosalvi]

@eolivelli Thank you. No, actually it needs to be upgraded. Next release cycle

@aahmed-se @lhotari can you take a look at apache/bookkeeper#2582 - I tried to upgrade grpc for bookkeeper
