The Policy Servers failed to start after VMs outage. At start time, they all reports the error:
[11588/-196843824][Thu Jun 25 2020 09:49:13][XPSObject.cpp:3534][setParent][ERROR][CA-SM-Assert] Assert failed: pParent
Exactly the same two objects were marked for deletion with xpsTombstone:
xpsNumber=0000000794,ou=XPS,ou=policysvr4,ou=siteminder,ou=netegrity,dc=example,dc=com
xpsNumber=0000000791,ou=XPS,ou=policysvr4,ou=siteminder,ou=netegrity,dc=example,dc=com
Removal of xpsTombstone attribute allowed to start Policy Server.
This problem wouldn't happen with a fresh new installation of Policy Server and Policy Store.
