I have a Glassfish 4 server with 4 domains running.
A minimum of once a day, some domin just dies without a single entry in the log files. I restart it with asadmin start-domain domainxxx and it works fine again.
All domains are running one single app, while one domain is also running a few additional apps.
The system did run without problem on Glassfish 3.
Since I don't know whats happening - no logs, nothing - I don't know where to start.
Any suggestions there to start looking?
GlassFish Server Open Source Edition 4.0 (build 89)
Ubuntu 14.04 LTS

I recently had to reinstall IntelliJ IDEA, and ever since then, I've been unable to run this one app that runs on Payara. I have Payara 5.2022.3 (full) installed and the project is using java 11.
This is the server log:
Artifact my_project-ear:ear exploded: Waiting for server connection to start artifact deployment…
Detected server admin port: 4848
Detected server http port: 8080
And then nothing happens.
And if I terminate the process I get a message:
Application Server was not connected before run configuration stop, reason: Unable to ping server at localhost:4848
Based on my observation it seems like a process starts running on port 4848 for a few seconds but then stops abruptly.
I checked the CrashDumps and here is the .dpm file in question.

I'd already tried:
Running it on a different port./ Checking if there was not a process blocking used ports.
"Renewing" the domain.xml in case it was corrupted somehow.
Using different JDK.
Reinstalling Windows
I'm positive there is no problem with the app's code (seen a friend run it on his computer today) and I also think no changes happened to the run/debug configuration or the payara and domain configuration ever since it was working before the IDEA reinstall.
(I'm also very new to payara, and software development in general, so I'm not quite as skilled in solving this kind of problem.)
Thank you for all your answers.
It looks like a bug in the Java version/vendor you are using which is causing the crash of the process. Updating to a more recent Java build or to a different JVM vendor should help.
hai friends i was trying to run apache server in my windows10 system but it fails as it was used by some other process.I ran netstat -nao | find ":80" command and it says pid 1900.But I cant find the process with pid 1900 in the task manager.What should i do.?Please help me as i'm a beginner.
Hi i have a similar issue with tomcat8.
If i restart server everything works fine. If restart tomcat service the ports seem busy.
I'm testing it but i'm pretty sure that should be related with some recent microsoft update, because 2 days ago there's any problem.
I'm tryng to uninstall last updates but i'm in a production server and it's not easy to reboot every time.
Can you test it?
Stay tuned
regards
Backstory: A couple of years ago my group changed the server on which coldfusion runs to Apache instead of IIS. I changed my dev environment to run CF on Apache httpd and everything was fine. Later we changed the session variables to j2ee, but I have never been able to get j2ee to work on dev so I am still using regular session variables on dev. Lately I am getting session persistence failure on test but I can't reproduce on dev. In looking for differences in CF server settings between test and dev I discovered that test is running on Tomcat while dev is running on Apache httpd.
My problem real problem is how to get j2ee session vars to work on dev. My question right now is how do I change my server from Apache httpd to the Tomcat that is built in with CF 10? Is there a way to do this without starting over with a fresh install of CF 10 as those are the only instructions I can find?
System: Windows 7
IIS and Apache are not (for Coldfusion, anyway) application servers. They are your front-end web servers. Your 'application server' in this setup is the software running the "application" of Coldfusion via servlets, and that's Tomcat.
While it is possible to use CF's builtin Tomcat server as your front-end web server, it isn't advisable, and it's almost certainly got nothing to do with your problem. Apache is more than capable of doing what you need and a problem with J2EE session variables is going to be related either to your JVM (are you using more-or-less the same version as your production server?) or to Tomcat itself.
Think about how J2EE sessions work. A request comes in and hits your front-end server (httpd), which, presumabl through mod_proxy or mod_jk, hands that connection over to Tomcat. Until this happens, that your system is even running a JVM isn't relevant -- neither Apache nor IIS care about Java. I wouldn't go so far as to say that it's impossible for an Apache problem to be monkeying with your session variables, but it would be pretty low on my list of suspects.
Once Tomcat (and then CF) get involved, then your JVM is doing all the work, so that's where I'd look. I'd also have a look at CF logs and Tomcat logs.
To properly answer your question, though, if you want to remove Apache from the loop, you're looking at Tomcat's server.xml and web.xml in /cfusion/runtime/conf - you'd need it running on port 80 (or else reconfigure Apache to just pass all requests to Tomcat instead of only CFML, but that doesn't really do what you asked about since Apache is still involved). You'd also have to reproduce your entire Apache configuration in Tomcat, which I've never done and wouldn't recommend, but that's the direction you'd need to investigate.
Much better to work on solving your session problem. Killing Apache is just collateral damage here.
The thing is that I have running GeoServer on a Tomcat 7 instance on my server. I had to install Pentaho BI-Server for data warehouse, but i start the service of Pentaho and immediately GeoServer Services stoped.
I start to wonder what's went wrong and I found that the download of Pentaho has own Tomcat Server. So thats was the problem the tomcat server from pentaho starts and took the ports of Tomcat that was running.
My question is how to configure the two tomcat to work together.
Thanks to all.
The solution gave KNOWARTH is correct, I also guide me the next post to know what ports need to change:

Greats to all.
We are running Weblogic 7sp6. We have a working single node cluster with an Admin and two Managed servers. We are re-creating a 2nd standalone cluster on a 2nd server. We reinstalled Weblogic and have copied over all the configuration files to make thing. Its the same on both clusters. We changed all the references to IP and hostnames. We have used this method before without problems.
In the current case I can startup the Admin which listens on port 7001,7002. But when I try and startup either of the Managed servers it tells me that myserver1/2 is already up. (Managed Servers). I confirmed that myserver is configured to use port 7012,7013 and I cannot find any port conflicts especially because these exact ports worked on the first cluster. Any ideas of what else to look at? I have logged in the admin console and can see the ports are all unique. Thanks
The current version of WebLogic is 10.3. I'd strongly urge you to upgrade your WebLogic as soon as possible, especially if you're still using the version of JDK that it was certified for. If you're running JDK 1.4, you're crazy.
