> Reduce ThinClientLocatorHelper lock time
> ----------------------------------------
>
> Key: GEODE-8553
> URL: https://issues.apache.org/jira/browse/GEODE-8553
> Project: Geode
> Issue Type: Improvement
> Components: native client
> Affects Versions: 1.12.0, 1.13.0
> Reporter: Mario Salazar de Torres
> Assignee: Mario Salazar de Torres
> Priority: Major
> Labels: pull-request-available
>
> During my troublshootings, I've seen that locking m_locatorLock for the whole
> scope of the class function members might cause some inter-locks.
> Problem here and in many other places of the NC is that networking operations
> are performed while a mutex is locked. Therefore if *thread A* takes longer
> than expected in performing its network operation, it might block another one
> which does not requires any resource of the first *thread A*. Hence, the
> inter-lock.
> This improvement is the first one of a series regarding to lock scope
> reduction when it comes with code regarding networking in NC.
