AkousaProcessLookupErrorRaised when a given process (typically a PID) does not exist.
os.kill(), os.waitpid(), or another OS call referenced a process ID that has already exited, was never spawned, or that the current user has no permission to inspect. On POSIX systems this surfaces ESRCH from the underlying syscall.
Verify the PID is still alive before signalling it (e.g. wrap os.kill in a try/except ProcessLookupError). Refresh subprocess.Popen object state with poll() or wait() before sending signals. If the child died unexpectedly, inspect returncode and stderr to understand why.
struct.errorAn error occurred while packing or unpacking binary data with the struct module.
TypeError: missing required positional argumentA function was called without providing all required positional arguments.
FloatingPointErrorA floating point operation failed. Rarely seen unless fpectl is enabled.
ValueErrorA function received an argument of the right type but an inappropriate value.
BrokenPipeErrorAn attempt was made to write to a pipe or socket whose reading end has been closed.
FileExistsErrorAn operation failed because the file or directory already exists.
