I've been able to narrow down on my system that enabling "Evolution Data Server" for Access to the Google Calendar is the trigger for this memory issue. See the three screenshots. I even removed and reauthorized the Google account access with no change.
First screenshot shows the Evolution Data Service disabled and memory function is normal. Second is toggling the Evolution Data Service from off to on. After ~10-5 seconds memory consumption appears at a rapid rate. Third is after switching Evolution Data Service from on to off and killing the indicator-datetime-service process showing the memory issue no longer exists. If Evolution Data Server is not switched to off killing the indicator- datetime-service process only restarts memory levels at the initial value and consumption growth appears nearly immediately following its automatic resume. ** Attachment added: "Three screenshots before during and after" https://bugs.launchpad.net/ubuntu/+source/indicator-datetime/+bug/1633319/+attachment/4762228/+files/screenshots.tar.gz -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to indicator-datetime in Ubuntu. https://bugs.launchpad.net/bugs/1633319 Title: memory leak in indicator-datetime Status in indicator-datetime package in Ubuntu: Confirmed Bug description: After upgrading from 16.04 to 16.10 on the System76 Serval WS indicator-datetime-service is consuming all the system memory from 3.7GB up to 32 GB in 30 seconds. The system kills the indicator- datetime-service process and indicator-datetime-service restarts and memory consumption repeats until killed again. All swap memory is consumed in this pattern.
