I found a strange phenomenon: I get the count of old gc in the nodes stats every 5 minutes and take the difference between the two statistics as the number of old gc, howerver, I found that the number of old gc's difference is greater than 0 and did not find in node's log. so how es to count gc.collectors.old and is it corret?
