Am getting this continuous warnings related to cleanup:

Due to this elephant sql is complaining about too many multiple connections. Am using exposed version 0.29.1 and latest pgjdbc-ng:0.8.6. Please help me understand the issue and share any code snippet if any. Am opening db connection like below:

fun getDBConn(): Database? {
    if (DBConnection == null) {
      synchronized(this) {
        if (DBConnection == null) {
          try {
            DBConnection = DataBaseConnection.connectWithDb(
              Config.DB_URL,
              Config.DB_DRIVER,
              Config.DB_USERNAME,
              Config.DB_PASSWORD
            )
          } catch (e: Exception) {
            println("error while connecting to db $e")
            return null
          }
        }
      }
    }
    return DBConnection
  }

There are some related issues opened in pgjdbc-ng repo: Take a look at these : https://github.com/impossibl/pgjdbc-ng/issues/129 https://github.com/impossibl/pgjdbc-ng/issues/44

in exposed we are not dealing with pgjdbc directly. most likely its either issue in the way am using expose or there is some bug in expose. create this issue: https://github.com/JetBrains/Exposed/issues/1171
