Question

这种情况不定期发生，但是几乎每天提交用户凭据的用户都必须等待几分钟才能完成身份验证。浏览器正在等待响应。重新启动tomcat将在一段时间内有所帮助。 Postgresql运行良好，并且具有足够的容量来处理新连接。任何想法如何解决这个问题？我们在第二周与之抗争，我们几乎尝试了一切。

环境：

Tomcat 8.5.34
postgresql-42.2.5
Linux上的1.8.0_162-b12

配置

<Realm className="org.apache.catalina.realm.JDBCRealm" 
       connectionName="XXXXXX" connectionPassword="YYYYYYY" 
       connectionURL="jdbc:postgresql://10.100.123.10:5432/pmgviewer" 
       userRoleTable="userroles" userTable="tomcatusers"           
       roleNameCol="userrole" userCredCol="passwd" userNameCol="username" 
       driverName="org.postgresql.Driver" 
       maxActive="40" maxIdle="10" maxWait="10000" 
       validationQuery="SELECT 1" validationInterval="30000"
       testWhileIdle="true" testOnBorrow="true" testOnReturn="false"> 
       <CredentialHandler className="org.apache.catalina.realm.MessageDigestCredentialHandler" algorithm="SHA-256" /> 
</Realm>

Tomcat 8.5使用JDBCRealm冻结在j_security_check中
