Memory leak

[MikronT]

Program settings

Version: 0.0.31 (latest)
Command line: ./uashield --no-sandbox (doesn't start without --no-sandbox parameter)

Proxy: enabled
Max threads (just my preference): 128

The amount of threads doesn't matter because the same happens with 256 or even 32 threads.

Environment

Oracle VM VirtualBox (virtual machine)

OS (uname -a output): Linux kali 5.16.0-kali6-amd64 #1 SMP PREEMPT Debian 5.16.14-1kali2 (2022-03-23) x86_64 GNU/Linux
RAM: 3 GB

Behavior

When the program is running normally, the CPU utilization is about 20%, and the RAM usage is 1.5/3.0 GB.

After running for quite a bit, the program starts gradually eating all the memory available, and the CPU load rises to 100% immediately.

Memory usage per process right before the crash:

By the way, the program window doesn't respond anymore, and the terminal output is scrolling way faster than normal. Among the usual logs, there's superagent: double callback bug message appearing every few seconds.

Then the program runs out of memory, and the crash happens. Here's a message you can see in the terminal:

Tried to gather everything I noticed. Don't really sure what else I can provide, so here it is.

I already created issue about this on node-socks-proxy.
TooTallNate/node-socks-proxy-agent#93

[opengs]

And looks like there is issue in http-proxy-agent and https-proxy-agent . I'm trying to find it, but now we are on workarounds :D . I spend hours on this issue and looks like this problem not in uashield.

[MikronT]

The issue is still present in the latest release 1.0.6, but there's some new info about it. The process causing the system to hang is now the one with the --type=renderer argument.

Forgot to add some logs.

First, there's noticeable the worker count degradation with some errors. But when the thread count reaches 16, there're a lot more of the same errors thrown.

The log of errors is very long. This short snippet was captured at the moment the memory usage went up.
