web server intermittantly locks up when asp queries oracle DB

<i><b>Originally posted by : matt clark (mat_clark@ic24.net)</b></i><br />Has anyone had this fault. I query an access db and the web server never locks up but intermittantly when query Oracle database.<br />This happens on PWS and IIS. The only way to get the site working again is to shutdown, reset the PC.<br /><br />any ideas?<br /><br />cheers<br /><br />matt<br />
