Trying to load a configuration that references an encrypted SSL key file may fail if the first line of the SSL key file is blank. When this occurs, the system will report a vague error message: 01070711:3: basic_string::compare If this happens during an upgrade, the system will not load the configuration under the new software version, and will remain inoperative.


Configuration fails to load on upgrade with extremely unhelpful error message, and absolutely no indication as to what file was being processed at the time (or that this relates to a filestore file).


This can occur if an affected configuration is present on a system running BIG-IP v11.3.0 or earlier, and is upgraded to BIG-IP v11.4.0 through v12.1.1.


Remove the newlines at the beginning of any SSL key files that begin with a newline. During an upgrade scenario, edit the files in the filestore.
