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:

image

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.

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.

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.
