memory usage grows with no limits

[ylexus]

On my Raspberry PI 5, when copying a single large file to the mounted Google Drive (using raspiBackup, if that's relevant), I can see rapid memory consumption until it fills all memory and starts using swap:

    PID USER      PR  NI    VIRT    RES    SHR S  %CPU  %MEM     TIME+ COMMAND

pi@rpi:~ $ google-drive-ocamlfuse -version
google-drive-ocamlfuse, version 0.7.30

Please help diagnose the issue.

Can confirm. Have this running on a remote Server and today I noticed that 50% of Memory was full. Upon further investigation, google-drive-ocamlfuse used 55GB
