SymptomsParallels Panel utility "ifmng" fails with segmentation fault:
~# /usr/local/psa/admin/bin/ifmng --new <interface> <ip> <netmask>
CauseIt is due to an issue with connectivity between different parts of system libraries.
ResolutionThe problem will be fixed in future update of Parallels Panel that will be released after version 9.2.3.
Hotfix for version 9.2.3 is in the attachment. To install the hotfix download the archive attached and unpack it. In resulted directory find binary ifmng for your operating system <OS> and architecture <ARCH> and replace /usr/local/psa/admin/sbin/ifmng with it.
