Blocked ConcurrentUpdateSolrClient

Hello 

I am trying to update larger amounts of Documents (mostly ADD/DELETE) through various threads. 

After a certain amount of time (a few hours) all my threads get stuck at 


taskExecutor-46" prio=5 tid=0x268 nid=0x10c BLOCKED             owned by taskExecutor-9 Id=230 - stats: cpu=2788 blk=-1 wait=-1
java.lang.Thread.State: BLOCKED
                at org.apache.solr.client.solrj.impl.ConcurrentUpdateSolrClient.blockUntilFinished(ConcurrentUpdateSolrClient.java:429)
                - waiting to lock org.apache.solr.client.solrj.impl.ConcurrentUpdateSolrServer@27a59c5b

                at org.apache.solr.client.solrj.SolrClient.deleteById(SolrClient.java:731)

I am using solr 5.5.4. 

Does anyone else have this problem ? 

Best regards
