Hello, Community:
I use Solr with Windows servers, and cannot shutdown Solr successfully.
When I try to stop Solr using solr.cmd, which is kicked from Windows Task
Manager, it "looks" like Solr stops without any problem.
Here "looks" means that at least log file that Solr wrote does not seem to
have any error.
(I pasted a piece of the log where I believe "success" at the end of this
email )
However, next time I start up the Solr, I face the error message that says
"Address already in use."
This problem happens occasionally, happens a different server at irregular
time/date.
So, I could not simulate the situation yet.
I wonder why Solr could not shutdown successfully.
If anyone of you has faced a similar incident or knows a solution, then it
is very helpful to share your bits of advice.
Any clue will be very appreciated.
