I am using VMware ubunutu LTS 18 VM on windows 10 host. I installed ntp to sync the time to ntp. the system time (as seen from date) is correct. Before ntpd activation the warning messages were coming for every minute. After ntpd the message are probably 5-6 minutes apart.

The idea.log is

Sorry for delayed reply. This message appears when the system clock time "jumps" backwards - IDE checks this when dispatching AWT events (main events processing loop) for debugging purposes. It can not be disabled.

Please verify your system time is correctly working. Try enabling Ubuntu time sync, check e.g. https://linuxconfig.org/how-to-sync-time-on-ubuntu-18-04-bionic-beaver-linux#h6-3-enable-disable-time-synchronization

I'm also experiencing this with a parallel desktop ubuntu VM. The thing is very annoying because IDE hangs and you have to start lover again.

Also experiencing this using WSL as a container dev environment. PhpStorm freezes after one or two of these messages.
