Jan Høydahl resolved SOLR-17439.
--------------------------------
Assignee: Jan Høydahl
Resolution: Not A Problem
It works, you just have to find the PID of the JAVA process running Solr.
Say you "docker exec" into the running solr container, then run "ps -ef",
you'll see the list of PIDs. On one of my containers it was PID 14. Then use
that PID.
Closing. In the future, please ask questions like this on the
[email protected] mailing list, not in JIRA.

> Affects Versions: 9.6.1
> Reporter: Roland Müller
> Assignee: Jan Høydahl
> Priority: Major
>
> I am running the solr:9.6.1 Docker image and want to create a heap dump.
> According to the documentation this should be possible using jattach:
> [https://solr.apache.org/guide/solr/latest/deployment-guide/solr-in-docker.html#debugging-with-jattach]
> If I open a shell in the container and enter the sample command from the
> documentation, this is what I get:
> {noformat}
> $ jattach 10 threaddump
> Process 10 not found{noformat}
> using the default PID 1, there is a different error:
> {noformat}
> $ jattach 1 threaddump
> Could not start attach mechanism: No such file or directory {noformat}
