Solr 4.8.1 Zookeeper 3.4.5 Centos 6.5 We are running into an issue where one of our environments is unable to successfully execute commands via the collection API. We found that we were unable to add new collections and after doing some digging found that even /solr/admin/collections?action=LIST sits for 180 seconds and then times out. Looking at Zookeeper in overseer/collection-queue-work you can see that tasks get queued up but never executed. Restarting Zookeeper and the solr instances seems to have no effect. Has anyone experienced anything similar or know how to recover from this state?
Thank you, Jonathan Hutchins
