heap dump failed

Postby kideok » Fri Jan 03, 2020 5:38 am

I connected remote docker container running on ec2 instance to capture mem snapshot.
When I try to capture it, YourKit program returned below error message.
And, ec2 was suddenly terminated with below message.
State transition reason: User initiated (2020-01-03 02:56:17 GMT)
State transition reason message: Client.UserInitiatedShutdown: User initiated shutdown

Run Environment:
- use YourKit-JavaProfiler-2019.8
- use docker container on ec2 instance.
- start agent with option:
- start profiler program with option: (~.yjp/ui.ini)

Please let me know if you have any comments.
Thank you.

Profiler agent cannot terminate EC2 instance. Is it reproducible? Most probably snapshot capturing takes a long time and profiler UI disconnects by timeout. This is absolutely harmless and you should be able to re-connect to profiled application as soon as snapshot is written to disk.
