系統java撰寫,使用了druid連接池,從遠程的postgresql資料庫獲取資料,不定時報錯org.postgresql.util.PSQLException: An I/O error occurred while sending to the backend. 每天報錯次數不定,少則幾次,多則2、3百次。
資料庫端日志HKT LOG: could not receive data from client: No connection could be made because the target machine actively refused it.
實在無法弄明白是什么原因導致的,求幫助
