Question about memory

Hi Everyone
I have an issue with memory.
I run the pi3 b+ with magic mirror with alexa

Modules on the mirror
Current weather
7 day forecast weather
Movie info
Google calendar
Also use wireless keyboard and usb extension in case I want to plug in flash drive in the usb slots. After a months time mirror goes into error sayin run out of memory and cache full. After a reboot everything loaded again all good.
Is there a module or tool to use to clean cache and memory or am I doing something wrong.
Hope I explained it properly and so you can understand newbie here.
Thank you Dave
