Warm CPU
The problem was that the CPU in my computer was going warm because too little air flow.
The reason for bad air flow was dirt on the cooling channels (between the wings) of the metal temperature sink.
After taking it out and cleaning it with a vacuum cleaner, the temperature went down to a normal value and the bug message has not come again.
