 ## Dumping the memory configuration, virtual processor register state and memory contents on a crash or unexpected VM Exit
 
-To dump the details of the memory configuration, the virtual processors register state and the contents of the VM memory set the feature `dump_on_crash` and run a debug build. This will result in a dump file being created in the temporary directory. The name and location of the dump file will be printed to the console and logged as an error message.

 There are no tools at this time to analyze the dump file, but it can be useful for debugging.

 The sample will run and generate trace data until any key is pressed.
 
 To view the trace data, leave the example running and use the jaegertracing/all-in-one container image with the following command:
 
 ```console
- docker run -d --name jaeger -e COLLECTOR_OTLP_ENABLED=true -p 4317:4317 -p 16686:16686 jaegertracing/all-in-one:1.51
+ docker run -d --name jaeger -e COLLECTOR_OTLP_ENABLED=true -p 4317:4317 -p 16686:16686 jaegertracing/all-in-one:1.60
 ```
 
 NOTE: when running this on windows that this is a linux container, so you will need to ensure that docker is configured to run linux containers using WSL2. Alternatively, you can download the Jaeger binaries from [here](https://www.jaegertracing.io/download/). Extract the archive and run the `jaeger-all-in-one` executable as follows:
