How to fix termux error phantom process signal 9 in android phone

What is Termux?

Termux is one of the finest Android terminal emulators without being minimally intrusive, offering a Linux environment. It enables one to run a full-fledged and complete Linux distribution on Android. Termux is complete with a package manager and shell access, and the possibility of installing and running different command-line applications.

What is a Ghost Process?

A phantom process Is defined as a process that runs in the background despite the user's assumption that it has already been killed. Such processes consume huge amounts of system resources, such as CPU cycles and memory.

This considerably degrading the performance of the device and decreasing battery life.

Why Do Phantom Processes Happen in Termux?

One of the reasons behind phantom processes in Termux is:

  1. Wrong Termination

In case the process is not killed properly, it may run in the background. For instance, this occurs in a scenario whereby a process is killed without properly cleaning up.

2. Background Tasks:

If the running tasks are in the background, and not managed properly, then it may lead to phantom processes. Normally, most users run scripts or commands which spawn background processes without monitoring them.

3. System Constraints

The Android memory management system can sometimes kill processes to free resources, and the processes can occasionally live a life of their own in an inconsistent state.

4. Misconfigured Scripts :

Scripts mistreated at termination may lead to orphaned processes. This might include, but is not limited to, failing to use proper exit traps or cleanup routines.

5. Software Bugs :

This might further be caused by bugs in the applications or the scripts running in Termux. Comprehending the causes can guide users in taking appropriate measures on preventing and handling phantom processes on Termux so that their Android device runs smoothly and efficiently.
