One of my services is deadlocked, I can't print the stack information. Is there any way to troubleshoot the problem?

I am trying to start a jBoss 5.1.0.GA instance and the output console is hanging on the [ProfileServiceBootstrap] Loading profile: ProfileKey#3f5f852e[domain=default, server=default, name=default] line.
The jBoss instance is copied from a remote server on which it works well.
There is not so much work logged (no more than 50 rows) and No error is displayed in console while starting up.
I understand that there may be some dependencies/connections/etc that it needs and are not satisfied, but I would expect an error to be thrown. Instead, it only hangs, without any other issue being reported.
I hope that this message will sound familiar to others that have worked more with older versions of jBoss and may direct me to investigate potential root causes.
Not proud of my findings... :) the issue was in fact that the logs were set not to write into the console. So, after looking for other log files, I found that the server started with the very well known statement Started in 1m:21s:836ms...
It is not really an issue nor an answer, but I leave this here in case others will find themselves in the same "I do not see the logs" situation (which should be also the title).
Note: in order logs to be shown, I have modified /server/default/conf/jboss-log4j.xml
I am using Docker and ELK stack. And using date and grok filters to parse a custom logs.
During this experiment I found _grokparsefailure in the Kibana document.
I am trying to investigate more details, why Grok failed parsing the string.
I tried to use Logstash docker logs. But could not find any trace.
Is there any way to see the reasons behind grok parsing errors
Thanks, Raghu
Copy the message for the failed parsing and head to the Grok Debugger in the Dev Tools with your grok pattern. There you can debug what as going wrong.
We are having exception thrown on Production that causes the w3wp process to crash. To figure out the faulted code, we configured the Debug Diag that is creating dump file when exception occur. Then we are trying to run the dump file with WinDbg to obtain the Stack Trace to figure out the faulted code but this is what we are experiencing after opening the dump file and running the required commands.
As you can see in the image above, it's not giving the stack trace after running the commands, I'm not sure what I'm missing
UPDATE
After running a command twice as suggested in the comments, I'm able to get the stack trace. But seems like there is no faulted code pointed out in the stack instead there is a long list of underlying framework in the stack. Below is the snapshot for the start of stack. Not sure how to identify the error. Any suggestion or I may need to open separate Question for this?
I am running a java program on my machine. I print the stack trace on console whenever an exception occurs. Where can i find the logs of those stack trace?
By default prints to console, this won't be written to file. If you want it in file, you need to do Run Configurations--->Common--->Select 'File' and file location. Then you will see your stacktrace in that file.
NLog has an internal log that the developer can use to troubleshoot issues with logging. Does Enterprise Library Logging have anything like that that I can use to figure out why my log messages aren't going anywhere?
There's a "Logging Errors and Warnings" special category. If there's a problem with the logging infrastructure itself, it'll get logged there. You can point this at any trace listener - by default it goes to the Windows event log.
Of course, if you have a problem with the trace listener for the errors, things get lost. There's only so many turtles you can stack on this one.
