there is answer from Thomas (tsegismont)

OK so it happens when you restart nodes, and I guess you restart a lot of them at the same time. One way to avoid loosing clustered data (event bus subscriptions and haInfo) is to increase the number of backups for the corresponding multimap (__vertx.subs) and map (__vertx.haInfo). Beware that versions up to 3.3.3 have a bug in the default cluster setup file (vert-x3/vertx-hazelcast@4b6e6f8)

We are working for a fix in 3.4

it could be cause for problem because during updating apps we have bash script which stops all apps and copies new jars and starts them, maybe old subs are left in consul __vertx.subs/haInfo
