Today I came across the same problem on L730 when I was calling where the phone rebooted w/o any notice. Previously I transferred all my apps from sd card to phone memory and free space was 1.7GB. I think it is a likely indicator on low memory. then, I transferred all rarely used apps and games to sd card and thus at the moment the issue is resolved. So free space increased from 1.7 to 2.5GB. Try moving rarely used apps or games to sd card. Shut down your phone and power on the phone again.
