Public bug reported:

Ubuntu 15.10 contains Archive::Zip v 1.49 that apparently has a bug that
creating/updating a zip archive file does not close it , and creating
many files generates "too many open files" error similar to this -

IO error: Can't open <.......>: Too many open files at /usr/share/perl5/Archive/Zip/FileMember.pm line 40.

Archive::Zip::Archive::overwrite(Archive::Zip::Archive=HASH(0x242eda8)) called at ./arcoper.pl line 57

lsof -p <pid>    shows all /tmp/*zip files deleted, but still open, up to max open files  (1000  which is system default)
Increasing number of files in limits.conf makes the problem generate less frequently.

installing latest version 1.56  from cpan fixes the problem - Using many
zip files correctly  closes them, does not generate errors, and lsof -p
<pid> shows only several files (less than 20)
