Looks like I'm running into: https://rt.cpan.org/Public/Bug/Display.html?id=122988
which was reported back in 9/2017. There doesn't seem to be a resolution to it? I diff'd 2.0.10 (released in 10/2016) against current svn head, and there really don't seem to be any changes of significance. Is mod_perl still under active development/being maintained? Any thoughts on this problem? Thanks much... -------------8<---------- Start Bug Report ------------8<---------- 1.
