------------------------------------
Hi flavio,
Ideally, I would like to have 932 part of 3.3.3 as well. But since 932 is not a
blocker (and not approved yet), I understand if it doesn't get in 3.3.3.
The order/dependency of patches that you have described is correct. Patch for
932 in a way depends on 880, but it will override 880 since it includes a fix
for 880 as well. So we won't have to do any additional "merge" of 880 with 932.
We will first commit 880 and then 932 to trunk.
Also, I think patch for 900 needs to go in 3.3.3.

> We're seeing an issue where one server in the ensemble has a steady growing
> number of QuorumCnxManager$SendWorker threads up to a point where the OS runs
> out of native threads, and at the same time we see a lot of exceptions in the
> logs. This is on 3.2.2 and our config looks like:
> {noformat}
> tickTime=3000
> dataDir=/somewhere_thats_not_tmp
> clientPort=2181
> initLimit=10
> syncLimit=5
> server.0=sv4borg9:2888:3888
> server.1=sv4borg10:2888:3888
> server.2=sv4borg11:2888:3888
> server.3=sv4borg12:2888:3888
> server.4=sv4borg13:2888:3888
> {noformat}
> The issue is on the first server. I'm going to attach threads dumps and logs
> in moment.
