SymptomsWhen creating a container via Parallels Virtual Automation Management Node it always has tcpsndbuf, tcprcvbuf, othersockbuf and dgramrcvbuf limits configured even though these limits were not set during container creation wizard.
CauseThis behavior was needed for Parallels Virtuozzo Containers for Linux prior to 4.7. With Parallels Virtuozzo Containers 4.7, Parallels Server Bare Metal 5.0 and Parallels Cloud Server it is not needed, because with vSwap these parameters are set to unlimited by default. This behavior is corrected in Parallels Virtual Automation 6.0.
