Network setup? Has a firewall appliance? It may drop the connection if
there is no traffic for a while. E.g. between the nodes. That may cause all
sorts of fun events.
And if you were watching it and maybe doing some test requests, that resets
the timeout value.
Something like wireshark may catch this kind of situations. Both actively
by examining the live connection and seeing the device IDs participating in
it (because firewall will be a piggy in a middle) and by checking if
connection was aborted just as Solr shutdown trying to use it. The timeout
itself will be silent, it is attempt to use connection after will get TCP
Fin (or some such).
JDBC pools used to get this issue a lot. So if all else fails, check this
option.
