cabi_external probe version 3.32 is resynching the cabi users in a regular interval.
When it is integrated into cabi that has spectrum integrated as well it is deleting all spectrum users from cabi.
The cabi_external probe 3.32 synchronizes the users periodically. To do this it deletes the users and recreates them.
In this case it deletes the spectrum users as well but does not recreate it.
fix will be build by engineering team. If you see this case please contact support for further information about the status of the fix.
