Operating system: Linux Mandrake 8 & RH6.2
PHP version: 4.0.6
PHP Bug Type: OCI8 related
Bug description: Every 5-10 page requests to page with OCI8 calls ends in
segmentation fault
Standard Oracle/OCI calls which work fine and then every 5-10 hits at the
page the page doesn't return correctly and then a segmentation error
follows. Checking the error_log shows the frequency of the problem is quite
high, when requesting the page in quick succession.
