Hi, I have long searched and haven't found any real hint how to solve my problem, so I am adressing you.
Here are my specifications: Server version: Apache Tomcat/8.5.15 Server built: May 5 2017 11:03:04 UTC Server number: 8.5.15.0 OS Name: Windows Server 2012 OS Version: 6.2 Architecture: amd64 Java Home: C:\Program Files\Java\jre7 JVM Version: 1.7.0_25-b17 JVM Vendor: Oracle Corporation The tomcat connector I am using has no custom configuration: <Connector port="8080" redirectPort="8443" protocol="HTTP/1.1"/> I have a PHP Javabridge app (runs PHP CGI to access JAVA functions) running on tomcat and it's beeing accessed solely through localhost from other PHP scripts running on IIS. It goes as follows: 1. Request sent to IIS 2. Run PHP on IIS, process the request and delegates a part of the processing to tomcat 3. Access tomcat through HTTP on localhost:8080 and wait maximum 60s for the response, retry up to 3 times 4. Run PHP on tomcat, process the request and send data back to the original PHP process on IIS (on 2.) 5. On IIS read the response from tomcat, process it and send a response to the original request (on 1.) For 99% of the time it goes well, we have around 500+ requests beeing succesfully processed. BUT aprox. once a day there are around 4 requests to tomcat within 3 minutes or so that aren't receiving any response at all (I have setup a 60s timeout in the IIS PHP process, usually the tomcat process takes up to 10s to respond). The strange thing is, those failed requests with no response are logged in the tomcat access logs with a 500 http connection error all at the same time (although they begun with 1-2 min difference) and after 8 to 24 hours (the URL is alway unique, so I know for sure). In the JAVA logs I can see a "java.net.SocketException: Connection reset", which is logical, as the PHP process on IIS closed the connection after the 60s timeout. I tried to set this timeout to infinite, with the result that the PHP process on IIS waited between 8 and 24 hours, only to get a 500 from tomcat. This time I got in the JAVA logs a "java.net.SocketException: Connection reset by peer" (notice the difference "by peer"). I hope I described my problem accurate enough. I'm out of ideas and I'm grateful for any insight!
