Subject Socket \ Connection Timeout Values
Date Thu, 03 Sep 2015 06:06:44 GMT

I wanted to ask about the implications of different timeout values one can 

For example:
>From what I see in the code, the default socket timeout value for Solr is 
Does that mean Solr nodes will wait to update \ receive update from each 
other without any timeout?
In other words, can the following scenario happen:
1. One solr node becomes very slow for some reason, but is still 
considered alive in ZK.
2. Other servers in the cluster try to update \ receive updates from this 
node, but do not get responds.
3. Since there's no timeout defined, all nodes in the cluster will 
eventually become unresponsive (when the thread pool is exhausted).

I could not find a detailed documentation about the subject, so will 
appreciate a clarification of the different timeouts and their roles.

Thanks you,
