Hello!
I'm trying to get Capture Memory snapshot on remote machine but keep getting "read timed out" and it crash/close the connection after that.

Snapshot capture should eventually finish, even if there are communication timeouts happen.

Does the process keep running?
If it instead terminates, is a crash log file created by the JVM? What are the last lines in the profiler agent log?

Could you please provide the agent log file in full. You can send it to support@yourkit.com

To increase the timeout thresholds, please add corresponding properties as described here:
