Hello! I'm trying Koha on a small fedora 23 virtual machine for testing (500 MB RAM, 1 core) and I often get this error in the web interface: ---- Software error: ERROR LOADING MODULE: Date::Manip::DM6 at /usr/share/perl5/vendor_perl/Date/Manip.pm line 34. Compilation failed in require at /usr/share/perl5/vendor_perl/C4/Overdues.pm line 25. BEGIN failed--compilation aborted at /usr/share/perl5/vendor_perl/C4/Overdues.pm line 25.

BEGIN failed--compilation aborted at /usr/share/koha/intranet/cgi-bin/tools/manage-marc-import.pl line 32. ---- The error is always identical and goes away with a refresh. When it happens I see I have less than 10 MB free memory so it really just seems a resource issue. I'll give Koha more memory :) but let me know if I missed something obvious. Federico (BEIC)
