DBD::Oracle - Connection Failed - out of memory

at the moment I'm going crazy with the same problem just
analyzed here: http://www.mail-archive.com/dbi-users@xxxxxxxx/msg25602.html

here again the problem:
I'm trying to test the connection betwwen my Sun SPARC 64bit - Solaris 10
and a remote Oracle DB.

----------
#!/usr/bin/perl
use DBI;
$dbh = DBI->connect("dbi:Oracle:host=...;sid=...;port=...","user","pwd");

----------
And the result is:

Out of memory!
Callback called exit.
END failed--call queue aborted.


I'm using the Oracle instantclient.

I noted that a possible solution is to install full client instead of
instant client, but in this case this is not possible, because of IT guys
:-(

Someone could suggest me a possible solution?
thanks
