VPND daemon on Virtual System constantly crashes after enabling Anti-Bot / Ant-Virus blade on Virtual System Technical Level
Symptoms
  • VPND daemon on Virtual System constantly crashes with core dump files after enabling Anti-Bot / Ant-Virus blade on Virtual System.

  • IPSec VPN blade is not enabled and VPN certificate was not yet created on this Virtual System.

  • Disabling Anti-Bot / Ant-Virus blade on Virtual System resolves the issue (VPND daemon does not crash).

  • VPND core dump files contain the following stack:
    Core was generated by `vpnd 0'.
    Program terminated with signal 11, Segmentation fault.
