I removed solr, and that didn't appear to really change anything.The hangup
still happened. I did watch catalina.out again, and I saw these lines right at
the hangup.
INFO: Starting Servlet Engine: Apache Tomcat/5.5.26
Apr 2, 2010 1:54:21 PM org.apache.catalina.core.StandardHost start
INFO: XML validation disabled
log4j:WARN No appenders could be found for logger
(org.apache.commons.digester.Digester.sax).
log4j:WARN Please initialize the log4j system properly.
It seems it's hanging at that line. I looked at my log4j.properties, and there
is nothing strange in it. It looks like the standard DSpace-supplied
log4j.properties file.
I googled around for an answer to the problem, but couldn't find anything
definite.

Hi Jason,
You can disable the solr webapp by removing the whole solr directory from
[tomcat]/webapps.
Your storage server may be slowing down the loading of the solr index, but 10
minutes sounds quite severe. You could test it by moving the indexes to the
local disk. They shouldn't get too big, so hopefully you'll have the space.
They are normally kept in [dspace]/solr so move them to a local disk, then edit
[tomcat]/solr/WEB-INF/web.xml
Look for:
env-entry
env-entry-namesolr/home/env-entry-name
env-entry-typejava.lang.String/env-entry-type
env-entry-value/dspace/solr/env-entry-value
/env-entry
And edit /dspace/solr as appropriate for the new location of your solr index.
Thanks,

Mark,
I'm not sure exactly how to disable the solr webapplication. Any suggestions?
The file access is pretty quick. We've never had any trouble before. We have
an app server for running the webapps and a storage server for everything
else.

It looks like the delay is before the solr servlet init log entry is
being called, IE before solr is loaded, disable the solr
webapplication from loading and test if the delay is still there
Likewise, what is the storage mount situation you are using here? If
file access is slow across this mount, that be slowing Lucene access
within Solr. You may try, moving your solr data directory onto the
local file system and testing if that speeds your loading time.
Finally, we have rather large solr indexes of statistics in production
that do not have load times anywhere near this degree of slowness.

I have confirmed from watching catalina.out that it consistently takes

Hi Jason,
How slow is slow? (Is it the handle server that is slow to startup, or
tomcat?)
