Can you try the patch I just put up on https://issues.apache.org/jira/browse/SOLR-1427 and let me know if it works when JMX is enabled?

Also, do you have warming queries setup?

It looks like this works as a fix for me as well. (I'm not currently
using JMX for anything anyway.)

Curiously, the single-core example solrconfig.xml also has "<jmx />",
but it doesn't seem to be a problem there.

Hi,

FWIW: disabling <jmx/> fixed this problem for me.

Thanks you!

Interesting... I still haven't been able to reproduce a hang with either jetty or tomcat.
I enabled replication and JMX... still nothing.

I found what looks like the same issue when I tried to install r815830 under Tomcat. (It works ok with the normal Jetty example/ start.jar.) I haven't checked the stack trace, but Tomcat would hang right after the
message

INFO: Adding  debug
component:org.apache.solr.handler.component.debugcompon...@1904e0d

showed up in the log.

I have a little more evidence about Yonik's theory that SOLR-1427 is
part of the cause. In particular, when I reverse-merged r815587 (the
commit for SOLR-1427) into (out of?) my r815830-based working copy,
then Tomcat was able to load Solr normally.

On a quick look, it looks like this was caused (or at least triggered
by)
https://issues.apache.org/jira/browse/SOLR-1427

Registering the bean in the SolrCore constructor causes it to
immediately turn around and ask for the stats which asks for a
searcher, which blocks.

Hi,

I am  testing EmbeddedSolrServer vs StreamingUpdateSolrServer  for
my crawlers using more or less recent Solr code and everything was
fine till today when I took the latest trunk code.
When I start my crawler I see a number of INFO outputs

and then the log/program stops.
