Camunda 8 Self Managed Run just hangs

paul.fearn · November 21, 2024, 3:55pm

I’ve downloaded Camunda 8 from Self-Managed download | Sign Up - Camunda (Windows 64bit.zip) and installed to c:\camunda and also installed JDK 23.0.1 but when I start it just hangs, see below:

C:\Camunda>c8run.exe start
Command: start
Java version is 23.0.1
Starting Elasticsearch 8.13.4…
(Hint: you can find the log output in the ‘elasticsearch.log’ file in the ‘log’ folder of your distribution.)

Elasticsearch has successfully been started.
C:\Camunda\camunda-zeebe-8.6.2\bin\camunda --spring.config.location=C:\Camunda\configuration
Waiting for Camunda to start. 24 retries left

When I check the Connectors.log I can see the Connection Refused error:
2024-11-17T08:54:59.337Z WARN 3416 — [ult-executor-33] io.camunda.zeebe.client.job.poller : Failed to activate jobs for worker AWS Textract and job type io.camunda:aws-textract:1

The following variables are all set correctly:
JAVA_HOME=JDK 23.0.1 folder
JAVA_VERSION=23.0.1
PATH=includes JDK 23.0.1\bin folder at start

Any help you can give me to get Camunda 8 running on Windows would be appreciated. Thanks

Hi @paul.fearn, welcome to the forums! The first suggestion we have is to try version 8.6.5 instead of 8.6.2. Here’s a direct download link: download. As with all software, small bugs get patched as we go, so trying the latest version may (hopefully!) resolve the issue!

ElasticSearch did not start on time, As the log stated, please check the elasticsearch logs exists in same logs folder as zeebe

paul.fearn · November 22, 2024, 8:32am

The log did say that ElasticSearch started, see below (there doesn’t appear to be any way for me to attach the logs to this ticket):

Full details of elasticsearch.log below for reference:

Tried 8.6.5 version and got exactly the same result:
C:\Camunda865>c8run.exe start
Command: start
Java version is 23.0.1
Starting Elasticsearch 8.13.4…
(Hint: you can find the log output in the ‘elasticsearch.log’ file in the ‘log’ folder of your distribution.)

Waiting for Elasticsearch to start. 12 retries left
Waiting for Elasticsearch to start. 11 retries left
Waiting for Elasticsearch to start. 10 retries left
Elasticsearch has successfully been started.

I found the same errors in the connectors.log and the camunda.log as per the details on this ticket.

cpbpm · November 22, 2024, 9:36am

This is the issue. C8Run uses port 8080, this was used by some other application apart from C8Run. Please make sure port is not used before starting C8Run.

paul.fearn · November 22, 2024, 10:41am

Big thanks for your help.

I used gthe windows commands below to identify the process that was listening on port 8080 and then uninstalled it.

– Use Netstat command to find the process id that is listening on port 8080
netstat -aon | findstr 8080
– Use Tasklist command to find details of the process that is listening on port 8080
tasklist | findstr 4460

In my case, it was the following process that was consuming port 8080 and blocking Camunda from starting:
