In general, we cannot avoid this in real world. It's important to make vmcore valid even in case of ENOSPC in the sense that at least generated part of vmcore can correctly be analized by crash. I agree. Dealing with ENOSPC makes sense. Save as much as possible and display a warning message that dump got truncated. Still dump file should be readable by "crash". That way we will not lose the whole dump and whatever has been saved, might be sufficient to analyze the dump. Thanks Vivek
