Hi Yury, You could try checking out the details command of the replication handler: http://slave_host:port/solr/replication?command=details which has information such as "isReplicating".
You could also look at the script attached to this issue which shows a thorough check of a slaves replication status which could be polled for to trigger a restart if there is an error.
