Oracle 10g: Special characters are not correctly returned 30 minutes

Dear all,

I'm noticing a very strange problem with my Apache/PHP/Oracle
installation. Imediatelly after an Apache restart, it all works OK. But,
~30 minutes later, all the special characters (namely, portuguese
accentuated characters) obtained from the DB disappear and are replaced
by other chars like "?".
It seems to be a PHP-Oracle interface problem, given that all the
characters are always OK when the connection is made through TOAD.

The variables ORACLE_HOME e NLS_LANG are defined with the following values:

ORACLE_HOME=/export/ORACLE/OraHome1
NLS_LANG=American_America.WE8ISO8859P15

Does anyone have a clue on what it's happening?

My system: Apache 2.0.52 + PHP 4.3.11 + Oracle 10g (through OCI8)

Thanks in advance.

Cheers,
Paulo Sousa
