When attempting to upgrade to 11.5.0 or later, from an earlier release, some .ucs files may cause the system to run out of memory, and the kernel to kill the process. You may also see an error: "UCS application failed; unknown cause."
It can be impossible to upgrade the software image to 11.5.0 or later because the config fixup exits in error.
In the .ucs file, in bigip.conf, is a section like this: ltm profile client-ssl /Common/my-clientssl { ... defaults-from /Common/wom-default-clientssl ... } The problem happens because /Common/wom-default-clientssl and /Common/clientssl-insecure-compatible was not defined in a couple of our fixup scripts, resulting in infinite recursion in another fixup script.
A workaround is to change instances of "wom-default-clientssl" and "clientssl-insecure-compatible" to "clientssl" in the configuration files in the UCS archive.
"wom-default-clientssl" and "clientssl-insecure-compatible" were added to two fixup scripts, and code to prevent infinite recursion was added to another script.
