Given that there is no actual useful/hard data in the above the chances
of there being a relevant answer in return is doubtful.

Also given your subsequent post the major version you are using is
nearing 1 year past EOL and is 21 minor releases behind the last release
in the series. At the very least you need to bring it up to the last
minor release.
