Overseer consume extra memory usage after upgrade

[buzzlightyear2k]

Im running the app which use Overseer to perform self-upgrade. My app is running as a systemd service in Ubuntu. After update my app suddenly consume extra memory usage.When i restart the service the memory usage backs to normal. Does anyone encounter the same problem ?

• Before upgrade:

Update

I figure out the cache memory is the problem. Does Overseer cache data somewhere while perform upgrade ?
