Subject Re: Lock timed out 2 worker running
Date Mon, 03 Aug 2009 06:20:34 GMT
Hi Chris,

Sorry for the very late reply. As a work around we sent the locking to
single and we turned-off one of our workers. And to answer your question,
please see below:

Yep, we are running out-of-the-bo solr installation using tomcat as servel
container. Both of our index workers are using SolrJ to send update to Solr.

Nope, everything is out-of-the-box.

Actually there is another 3rd apps (an instance of index workers but not all
functionality are enabled). It only send a delete request to Solr but it's
via SolrJ as well. And I double checked that all this workers are hitting
the same solr base url

 CentOS 5.2 local disk.

Yep, I can't find the logs but it's something like can't obtain lock for
<somefile>.lck Need to delete that fiile in order to start the solr properly

The later 1.3.0 release.

I'm not sure what you mean by normal usage. But aside from the 2 workers (or
3), we are running rsync and snapshooter every 30 secs.  and on the slave,
we are running snappuller every 30 secs. as well. This is a requirement to
pick up the latest changes right away.

Thanks,
