PHP 4.0 Bug #7501 Updated: apache dies at startup with php enabled

ID: 7501 Updated by: rasmus Reported By: traindrv_@hotmail.com Status: Closed Bug Type: Apache related Assigned To: Comments: This is a glibc-2.1.x bug triggered by loading a dynamic library linked against pthreads into a binary that is not linked against pthreads. Identify which 3rd-party client library needs pthreads. Candidates are libmysqlclient.so and Oracle's libclntsh.so. In the MySQL case, get a non-pthreads version of the library. In the Oracle case, recompile your Apache httpd against pthreads since there is no non-pthreads Oracle client lib available (unless you want to downgrade to 8.0.5).

To make it work the following sequence of operations are needed: - comment out php module from httpd.conf - apachectl start - uncomment php moudle in httpd.conf - apachectl restart Then PHP works very happily. It occasionally manages to load on start-up, but very seldom. We've seen this problem on a couple of machines.
