OTR timeout when using more than one application instances

[frdmn]

Server log files:

[...]
rocketchat_1          | Meteor ➔ method deleteOldOTRMessages -> userId: 4ZtGQjwZ7PDrRNTYa, arguments: ["4ZtGQjwZ7PDrRNTYa5WPGDAB6cBiMWQqaa"]
[...]

Nothing in client console.

Seems to work without any issues when only one Rocket.Chat instance is in use.
