ID: 16538 Updated by: jerry.zhao@vanderbilt.edu Reported By: jerry.zhao@vanderbilt.edu -Status: Feedback +Status: Open Bug Type: Session related Operating System: Solaris 7 PHP Version: 4.1.2 New Comment: You are right! I was returning a boolean false instead of "". Now everything works as it should be. Thanks! Previous Comments: ------------------------------------------------------------------------ [2002-05-02 10:21:45] yohgaki@php.net As in Manual, you are supposed to return string type always from read function. Did you do that? ------------------------------------------------------------------------ [2002-05-02 10:03:03] jerry.zhao@vanderbilt.edu I fixed the session problem by replacing all boolean values with "1" or "0" in the user defined session functions. There were still some "bus error" errors and other httpd process related issues, which went away after we upgraded to the latest Apache 1.3.24. ------------------------------------------------------------------------ [2002-04-11 06:22:43] sander@php.net To properly diagnose this bug, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". ------------------------------------------------------------------------ [2002-04-10 16:57:07] jerry.zhao@vanderbilt.edu We use mysql db as the store for session data. In the past one month or so, I have noticed that Apache generated some "Segmentation fault" or "Bus error" messages. I was finally able to single out the cause of these errors: a couple of php pages using session. When a new session is initiated, the session data is not stored in the mysql db at least 1 out of 5 times, which appears to be related to the segfault/bus errors. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=16538&edit=1
