[Koha] many files *_koha_3_00_00_107 after upgrade

[ghenry]

hello all,
into opensolaris, after upgrading from 2 to 3 (and 3.0.0 to 3.0.1), i 
have many files whose name finished by: _koha_3_00_00_107
Does it mean that something was wrong during the upgrade?
root at catalogue3:/usr/local/koha# find . -name "*_koha_3_00_00_107"|wc -l
     5992
root at catalogue3:/usr/local/koha# find . |wc -l
    49433

thanks in advance for help,

gerard
