Hi, The version is the 4.1
I'm not mixing deletes and adds, are only adds. I have a 4 nodes in 2 physical machines, 2 instances of tomcat in each machine. In this case the leader is located in a diferent physical machine that the replica. The collection has all shards in different nodes, I have not oversharding. The question of the stack I need install the visualvm and try to get the stack. I create the collection using the CORE API: LEADER curl http://192.168.20.48:8983/solr/admin/cores\?action\=CREATE\&name\=ST-0112\&collection\=ST-0112\&shard\=00\&collection.configName\=statisticsBucket-regular REPLICA curl http://192.168.20.50:8983/solr/admin/cores\?action\=CREATE\&name\=ST-0112\&collection\=ST-0112\&shard\=00\&collection.configName\=statisticsBucket-regular The data folders have the content: LEADER drwxr-xr-x 2 root root 4096 Jan 30 17:40 index drwxr-xr-x 2 root root 12288 Feb 5 13:28 index.20130130174052236 drwxr-xr-x 2 root root 36864 Mar 11 15:20 index.20130220001204140 -rw-r--r-- 1 root root 78 Feb 20 00:13 index.properties -rw-r--r-- 1 root root 251 Feb 20 00:13 replication.properties drwxr-xr-x 2 root root 4096 Mar 11 15:19 tlog REPLICA drwxr-xr-x 2 root root 4096 Mar 11 15:59 index.20130228105843631 -rw-r--r-- 1 root root 78 Feb 28 10:59 index.properties -rw-r--r-- 1 root root 208 Feb 28 10:59 replication.properties drwxr-xr-x 2 root root 4096 Mar 11 12:17 tlog ----- Best regards -- View this message in context: http://lucene.472066.n3.nabble.com/SolrCloud-update-timeout-tp4046348p4046385.html Sent from the Solr - User mailing list archive at Nabble.com.
