Hi, Below are few

Hi,

Below are few suggestions which might be helpful.
My guess is if you are building as-is from the source, the nodes that are being created are 'flat' nodes. This is because 'flat' is defined to be the standard node type. In mod_pubsub try changing

-define(STDNODE, <<"flat">>).

-define(STDNODE, <<"hometree">>).

and then recompile.

Also, as far as I know, dag is no more maintained. I could be wrong about this.
Hope this helps.

I also can't create nodes

I also can't create nodes whether on virtual or dag nodetree. I tried deleting database. I'm getting the following in error log:

[error] <0.844.0>@mod_pubsub:transaction_retry:4236 transaction return internal error: {'EXIT',{{badmatch,[<<"localhost">>]},[{mod_pubsub,serverhost,1,[{file,"src/mod_pubsub.erl"},{line,4012}]},{mod_pubsub,tree,1,[{file,"src/mod_pubsub.erl"},{line,4016}]},{mod_pubsub,tree_call,3,[{file,"src/mod_pubsub.erl"},{line,4131}]},{mod_pubsub,'-transaction/4-fun-0-',3,[{file,"src/mod_pubsub.erl"},{line,4183}]},{mnesia_tm,non_transaction,5,[{file,"mnesia_tm.erl"},{line,737}]},{mod_pubsub,transaction_retry,6,[{file,"src/mod_pubsub.erl"},{line,4210}]},{mod_pubsub,publish_item,7,[{file,"src/mod_pubsub.erl"},{line,2193}]},{mod_pubsub,iq_sm,3,[{file,"src/mod_pubsub.erl"},{line,1206}]}]}}

When i set nodetree attribute

gunjanm608 — Mon, 30 Nov 2015 17:03:17 +0000

When i set nodetree attribute in mod_pubsub to "dag" and default plugin to "dag", and if I try to create a collection or a leaf node, then the server returns with internal-server-error

The following is what is logged as the error. Even if i delete all pubsub related data in mnesia (rm var/lib/ejabberd/pubsub_index.DCD, pubsub_index.DCL, pubsub_item.DAT, pubsub_node.DCD, pubsub_node.DCL) and start afresh with nodetree and default plugin to "dag", i still get the same error.
