tg-crud: sometimes a long period steadily rising CPU usage occurs
Sometimes tg-crud starts to consume more and more CPU cycles over time. It looks like there are hanging threads, which could occupy a whole CPU core, like ocasinally there is anothe core occupied. !tgcrud-cpu-usage.png! This is visible in grafana, but there is no icinga monitoring which could trigger a warning. So this problem may be unrecognized over longer time. Restarting tomcat-crud helps. The second screenshot shows the ocurrences of this problem over one year. !tgcrud-cpu-one-year.png!
