Title: mssql_availability_groups: Parsing of section failed Class: fix Compatible: compat Component: checks Date: 1722418114 Edition: cre Level: 1 Version: 2.2.0p32 Provided with invalid lines `parse_mssql_availability_groups()` would crash with an exception ``` IndexError: list index out of range ``` Resulting in `Parsing of section mssql_availability_groups` error message in UI. This change makes `parse_mssql_availability_groups()` resilient to those lines by just ignoring them.
