100% CPU + Large/Fast Memory Leak #8

Open 3vi1 opened 3 years ago

3vi1 commented 3 years ago

CasterSoundBoard appears to work. But, randomly it will begin using 100% of one CPU core and then consumes all available memory (32GB). Perhaps something has changed with the newer Qt libraries to make a pre-existing problem more evident?

Basic system details

Qt 5.15.2 (x86_64-little_endian-lp64 shared (dynamic) release build; by GCC 10.2.1 20201207) on "xcb" OS: Ubuntu Hirsute Hippo (development branch) [linux version 5.8.0-25-generic]

CasterSoundboard version+commit: v1.0 BETA + commit 1a84315b3a3d4bdca1a4b784bd19460637f44438 Operating system: Ubuntu 21.04 (alpha) Desktop environment: KDE Plasma 5.20.5

Steps to reproduce

  1. Load a couple of soundboard tabs full of small sounds (<5 second wavs and mp3s).
  2. Play random sounds from the boards.

  3. Check CPU and watch memory utilization grow constantly - even when not playing sounds.

    High CPU Growing Memory Utilization

    The app will exhaust all memory if left running.

Is this project still maintained? I notice that a lot of issues have been added to the JupiterBroadcasting fork, but that fork doesn't appear to be under development.

The memory leak is actually worse than I first thought. I just loaded CasterSoundBoard, opened two tabs, and let it sit. It ran out the system out of memory 10 minutes later - without ever playing a sound. So, the leak is not in the playback functions.

The issue I was experiencing seems to be related to the tab data. I noticed the leak only happened if I loaded one of the two tabs, so I deleted the tab causing issues and created a new one. I've added most sounds back and the problem has not returned.
