Today when trying VNC to my Pi 3, I got an error saying “failed to fork cannot allocate memory”.
After some research, I found out that the Pi is running out of space
The Pi had 32GB SD with only Blynk on it, what take up all the space and how to clean those up?
You didn’t mention what type of Blynk you are using… a Client or Local Server? if Local Server, then it will probably be all the data built up over time.
Just remove whatever historical data you no longer want from your data folder.
Perhaps there are even too many backups in your backup folder.
My RPi folder structure for Blynk is as such… you will have to determine your own.
For example on my 8GB Netbook, running Mint GUI and my Blynk Server (now including my Blynk image storage/server, all under the /home sub-folder) …
Not sure how accurate, or if I was running it correct… as my system keeps telling me (for the last year+ ) that I usually have less then 10MB free space… yet it just keeps on working
