Memory leak in aMule 2.3.3 Debian Bullseye

[ngosang]

I have been using aMule 2.3.3 (Debian Bullseye package) for several months and I notice there is an important memory leak. I know this issue does not contain enough information to fix the problem but maybe it keeps all related issues in the same place.

I'm running aMule 24/7 in my server and I notice the RAM memory increases over the time without a reason. aMule is connected to 1 ed2k server and Kad network, just sharing files, not downloading anything. I only use amuled and amuleweb processes. As you can see in the screenshots below the issue is in amuled process.

To fix this issue I configured a cron task that restarts aMule every 2 days, if I don't, the memory keeps growing lineal.

Just after start

After 2 days

The memory leak is not huge, just 28 MB increase of RAM per day (24 hours), but it is meaningful if you are running in a Raspberry Pi with low RAM. It can crash your system eventually. I hope you can run some memory profiler in aMule to find and fix this issue.

Maybe related? Seems a release failed here.

@ngosang maybe not a problem of the amule, see this: raspberrypi/linux#5395

[ngosang]

@ogarcia It's not related.
I'm maintaining an Alpine Linux Docker image => https://github.com/ngosang/docker-amule
And I can reproduce the issue in x64 and arm64 servers. Furthermore, I don't have issues with the OOM killer.

Another temporary solution: disable obfuscation supported
