Some heights are stuck during performance tests

While working on https://github.com/omgnetwork/elixir-omg/issues/1600 [https://github.com/omgnetwork/elixir-omg/pull/1691], I discovered that some heights from watcher's status_get api are stuck.

At some point during byzantine events performance tests in the perf project, they just stop changing their values. The services are "block_getter" , "exit_finalizer" and "ife_exit_finalizer"

Locally everything works fine, only ci is affected.
