PHP is occasionally seg faulting

Im running php 5.0.4 with oracle 10g on Solaris 9 and apache 2.0.54. (I built with --with-oci8 so I am using the OCI stuff) I have a simple test page that does "select username from dba_users" and merely prints each username to the browser. It will work 1 time or sometimes 2 but then subsequent calls produce errors (in the browser) and the apache log gets this: [Tue Jul 19 16:01:10 2005] [notice] child pid 7105 exit signal Segmentation fault (11) [Tue Jul 19 16:02:18 2005] [notice] child pid 7107 exit signal Segmentation fault (11) [Tue Jul 19 16:02:19 2005] [notice] child pid 7110 exit signal Segmentation fault (11) Anyone have any ideas? Thx, CC
