We have started having an issue with our Visual Cron Server (9.3.0) where the memory on the server steadily rises all day long until the entire visual cron service locks up and we have to reboot the server. Do you have any playbook or instructions for ways to easily help us locate where this leak may be coming rom? It recently started a few days ago and we have not been able to narrow down a specific new job or anything that would cause this. About 1 hour after we perform the reboot, we see a drop in memory followed by a spike. This has stayed consistent across multiple reboots. The drops always occur exactly one hour after the reboot and then every hour after. You can see the memory graph below.

There are some logs that may be related as well but we are not sure what they may mean. The server name was crossed out.

Any help would be appreciated as rebooting our production server every day has been causing issues for us.

Hi,

Apologize for the delayed response on this matter. Could you see if you can reproduce this on our latest 9.4.0, please? If so, send us an email to support@visualcron.com as we are interested in getting to the bottom of this, if you are able to reproduce on our latest official version.
