Move vertex suddenly drops edges

2.2.7, Linux ubuntu

Expected behavior and actual behavior

When moving vertex from one class to another I would expect that those edges will not be removed.
This is mine code snippet:
OrientVertex beforeVertex;
OrientVertex afterVertex;
int bofore = beforeVertex.countEdges(Direction.IN, UserVoteOnPickle.LABEL);
activeGraph.command(new OCommandSQL("move vertex #11:545 to class:ExpiredPickle set expiredAt = ?")).execute(new Date());
int after = afterVertex.countEdges(Direction.IN, UserVoteOnPickle.LABEL);

create class User extends V;
create class Pickle extends V;
create class ActivePickle extends Pickle;
create class ExpiredPickle extends Pickle;
create property ExpiredPickle.expiredAt datetime;
create class UserVoteOnPickle extends E;
create property UserVoteOnPickle.out LINK User;
create property UserVoteOnPickle.in LINK Pickle;
ALTER PROPERTY UserVoteOnPickle.out MANDATORY TRUE;
ALTER PROPERTY UserVoteOnPickle.in MANDATORY TRUE;
CREATE INDEX UniqueUserVoteOnPickle ON UserVoteOnPickle(out,in) UNIQUE;

UserVoteOnPickle's are the edges which disappear.

Those are the logs I am getting after executing this code:

2016-10-06 13:21:27,118 INFO [request=] [uid=] [user=] [service=] - Votes count after: 0

Steps to reproduce the problem

I do not know exact steps to reproduce but it seems that it does not work only with large ammount of edges. As you see in mine logs vertex with two edges was able to keep them persited .. but those with more are lost.

Error did not occur with version 2.1, it started to occur after update to 2.2

Hi @lukaszkaleta

I managed to reproduce the problem, I'm on it

Thanks

Hi @lukaszkaleta

I just pushed a fix for this. The problem was limited to vertices with more that 40 edges (the threshold for RidBag Bonsai implementation)
The fix will be released with 2.2.12

Thanks
