HikariPool- Thread starvation or clock leap detected (housekeeper delta

Question

Here hikari conf:

jdbcUrl=jdbc:postgresql://some_ip/myProject
driverClassName=org.postgresql.Driver
username=username
password=pass
connectionTestQuery=SELECT CURRENT_TIMESTAMP
maximumPoolSize=3
connectionTimeout=20000

In my Kotlin project:

   lateinit var ds: HikariDataSource
   val dbConfig = HikariConfig("hikari.conf")
    ds = HikariDataSource(dbConfig)

     if (!insertQuery.isEmpty()) {
                    val connection = ds.connection
                    val insert = connection.prepareCall(insertQuery)
                    insert.execute()
                    insert.close()
                    connection.close()
                }

And it's work fine. Nice.

But sometime I get warning message in log like this:

2019-04-27 18:55:23,852 17519559 [HikariPool-1 housekeeper] WARN  com.zaxxer.hikari.pool.HikariPool - HikariPool-1 - Thread starvation or clock leap detected (housekeeper delta=5m30s164ms615µs200ns).

As result it stop insert new records to db.

If you are running on a mac and see this issue it's nothing to worry about and your laptop has gone to sleep.
