Description Stefan Gohmann univentionstaff 2014-11-06 07:31:47 CET
We got feedback about a high memory usage in the computerroom module.
Comment 1 Stefan Gohmann univentionstaff 2014-11-06 07:56:51 CET
ucs-school-umc-computerroom: r55415 (3.2) + r55417 (4.0)

* Delete the old ItalcComputer objects in order to free the memory
  (Bug #36469)

italc: r55416 (3.2) + r55419 (4.0)

* Free the framebuffer memory already while stopping the VNC
  connection. This will reduce the memory usage of our python italc
  interface (Bug #36469)

Changelog has been added: r55429

My tests were successful. While selecting a new room, the memory usage increases but the memory is freed by the garbage collector.
Comment 3 Stefan Gohmann univentionstaff 2014-11-06 17:35:14 CET
ucs-school-umc-computerroom: r55470

* Stop, close and delete the computer connections before clearing the
  dict. That should save memory and network connections (Bug #36469)
