This you can fix, by adding another account. When one account is in the queue the miner will switch to the next:
witness="account1"
witness="account2"
miner=["account1","key1"]
miner=["account2","key2"]
# name of witness controlled by this node (e.g. initwitness )
witness = "olib"
witness = "second"
# name of miner and its private key (e.g. ["account","WIF PRIVATE KEY"] )
miner = ["olib","xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"]
miner = ["second","xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"]
