Logcat not working on my LG G4 (H815)

I can't read the logcat from my phone. As an Android Developer, this is terrible for me. The message that I'm getting is:

logcat read failure

Looking the sources, it seems like a generic error:

Code from the source (Github, logcat.cpp)

while (!g_maxCount || (g_printCount < g_maxCount)) {



 struct log_msg log_msg;


 log_device_t* d;


 int ret = android_logger_list_read(logger_list, &log_msg);





 if (ret == 0) {



  logcat_panic(false, "read: unexpected EOF!\n");



 
}





 if (ret < 0) {



  if (ret == -EAGAIN) {



break;


  
}





  if (ret == -EIO) {



logcat_panic(false, "read: unexpected EOF!\n");



  
}



  if (ret == -EINVAL) {



logcat_panic(false, "read: unexpected length.\n");



  
}



  logcat_panic(false, "logcat read failure");



 
}

My phone is rooted and has the bootloader unlocked. I'm using stock kernel. I've no clues. Any ideas, something to try?

Thanks in advance
