UTL_HTTP ORA-00018 error

Hello,

I am trying to write a PL/SQL procedure that will loop through a list of URLs and determine whether or not they actually exist. For each URL, I'm performing the following sequence of procedure/function calls:  UTL_HTTP.BEGIN_REQUEST, UTL_HTTP.GET_RESPONSE, UTL_HTTP.END_RESPONSE. After about 675 iterations of the loop, I get the "ORA-00018: maximum number of sessions exceeded" exception. I'm not using persistent connection support. The basic loop follows. I would appreciate any help that you can provide.

Thanks,

Steve.

    UTL_HTTP.SET_DETAILED_EXCP_SUPPORT (TRUE);     UTL_HTTP.SET_PERSISTENT_CONN_SUPPORT (FALSE, 1);     FOR cImages IN c_add_files LOOP

• See if the image URL is valid. request := UTL_HTTP.BEGIN_REQUEST (URL => cImages.IAF_LOCATION, METHOD => 'GET'); UTL_HTTP.SET_HEADER (R => request, NAME => 'User-Agent', VALUE => 'Mozilla/4.0'); response := UTL_HTTP.GET_RESPONSE (r => request);

        IF response.STATUS_CODE <> UTL_HTTP.HTTP_OK THEN
            ...
        END IF;
        UTL_HTTP.END_RESPONSE (r => response);
