Understanding NIO connector

Hello everybody, I am trying to understand in which way tomcat is handling incoming connections. We have a spring boot application in production that is using tomcat embedded (version 8.x) and since we are experiencing some issues with Too Many Files open, we would like to understand properly in

Re: Trying to chase down "too many connection" problems with DB

*1) I think this is the really burning question in my mind: Why is the server opening NEW connections when there are dozens of them already open? Does this mean that (as I suspect) all those connections are abandoned? If so, why are they not getting cleaned up, when we have removeAbandoned set to

Re: Best way to find out how many DB connections that are open at any given time

Ciao Joleen, maybe you could retrieve this information connecting via JMX (JConsole, VisualVM) to the tomcat instances. According to the way the datasource is configured, you could find a JMX bean exposing this information. Before that, tomcat should be launched in a way JMX connections are

Ciao Nick, according to my own experience, I saw some logs at SEVERE very similar to what you posted here when I used hot deploy for a web application I worked on and that application used threadlocal variables and launched some threads that tomcat didn't control directly. These logs are part of

Issues with getRemoteAddress

Hi all, we're experiencing an issue with the getRemoteAddress method (HttpServletRequest). We don't know whether is something known depending on tomcat or if it's something malicious, affecting our servers. We have a filter that authorizes incoming requests using different patterns, one of these

Re: Issues with getRemoteAddress

Re: Tomcat 5.5.27, session lost, cookies

Ciao Diego! While working with cookies, we had some issues handling not valid characters. One of our legacy (non java) server was used to put a blank (' ') character as value of a cookie. But it seems that blank it's a forbidden char so tomcat was not able to parse the cookie value. Is it possible
