Hello,
I use Riak Java client (1.0.6) and riak-pb (1.2) versions. I see that a
thread stucks on reading socket from time to time in production. Basically
the thread is never released once it gets this state. Riak backend logs are
empty at the same time. Could you please look at the following stack trace?
I need an advise what can be wrong and how to investigate/solve the issue.
Thank you,
Konstantin.
