My tomcat server keeps processing some requests for more than 10 minutes. I stopped client which had triggered those requests but then also tomcat keeps processing those requests.
I have tried different settings for connectionTimeout property in server.xml file of tomcat but it is not working.
I would like to know how to configure tomcat such that tomcat kills/ stops processing requests which take longer than certain time like 10 seconds or 1 minute, etc.
From The Apache Tomcat Connector - Generic HowTo Timeouts
JK can also use a timeout on request replies. This timeout does not measure the full processing time of the response. Instead it controls, how much time between consecutive response packets is allowed.
In most cases, this is what one actually wants. Consider for example long running downloads. You would not be able to set an effective global reply timeout, because downloads could last for many minutes. Most applications though have limited processing time before starting to return the response. For those applications you could set an explicit reply timeout. Applications that do not harmonise with reply timeouts are batch type applications, data warehouse and reporting applications which are expected to observe long processing times.
If JK aborts waiting for a response, because a reply timeout fired, there is no way to stop processing on the backend. Although you free processing resources in your web server, the request will continue to run on the backend - without any way to send back a result once the reply timeout fired.
