Hi All, I am using 3 Solr instances behind an Amazon ELB with 1 shared. Serving data via Solr works as expected, however I noticed a few times a 503 error was poping up from the applications accessing Solr. Accessing Solr is done via the AWS ELB.
3 Zookeeper instances also run on the same instances as Solr on a separate disk. Solr version is 4.4. This issue seems to be a sporadic issue. Has anyone else observed this kind of behavior ? Thanks, Indika
