Hi all,
We have about 15 Kvstores running ok but sometimes I detect that we had a update problem because we don´t have all the filtered events there, we lose some... And we have to reload all the kvstore to fix it and again we have a fresh and updated kvstore version.
But I don't know why we have this problem, really, I can read this kind of error in _internal logs:

Have you seen that before?
We upgrade Kv stores every 5 minutes and a couple of them are very big (+770K lines)...
Perhaps Splunk/mongodb is still upgrading a Kvstore when we try to update it again?
Thanks a lot for your comments
Javier.
