Spark Profiler freezes server and then crashes.
TheNetherPug opened this issue ยท 2 comments
Server software: git-Purpur-1985
Spark version: 1.10.41
RAM: 1gb
CPU: Amd Ryzen 5
After around 20 minutes of uptime, running the command "/spark profiler open" or "/spark profiler stop" will freeze the server for a short period of time, and then crash it.

Please fix as soon as possible as this makes it very difficult to debug server lag causes. Thank you
