dbcheck.pl 0.99 issue with Perl 5.10

[L.M.J]

Hi

 I have to dist-upgrade my XYmon server from Ubuntu 64bits Hardy to Ibex
and now, my decheck.pl doesn't work anymore :
    Tue Dec 30 15:12:34 2008:ERROR on DB01: Timeout connecting to
DBI:Oracle:host=oraclesrv01;port=1522;sid=DB01!

    Tue Dec 30 15:12:34 2008:ERROR on DB04: Timeout connecting to
DBI:Oracle:host=oraclesrv01;port=1521;sid=DB04!

 Any ideas what could be wrong ?

  Thanks by advance!
