From: gg dot cwlee at gmail dot com Operating system: Windows XP PHP version: 5.2.12 PHP Bug Type: ODBC related Bug description: Some resource leak (odbc_connect and odbc_close) using dbase or Microsoft Acces Description: ------------ We have a resource leak problem when using Apache 2.2.11 and PHP 5.2.12 with odbc_connect() and odbc_close() functions on dbase or Microsoft Access. From my observe, it will leak some (Nonpaged) kernel Memory and some handles not free by the Apache(HTTPD.EXE). And I also tested no this resource leak problem on Apache 2.2.11 and PHP 5.2.0. Thanks.
