I have recently updated my Pi (apt-get update / upgrade / rpi-update) and this process also updated OwnCloud (for which my Pi is optimized for) from 5 to 6.0.0a.
From now on, when owncloud process starts, soffice.bin process uses nearly 100% cpu and the Pi stops responding (keyboard does not respond and ssh stops working). If I shutdown the power and restart, it becomes responsive again...until OwnCloud 6 starts working and using soffice.bin.
Any idea if CPU might be getting overloaded and causes this? Anyone using owncloud on the Pi with the same issue ? Thanks.
