PHP 4.0 Bug #5624: Can't make sessions work

From: david@interpont.hu Operating system: NT4 SP6 IIS4 PHP version: 4.0.1pl2 PHP Bug Type: Session related Bug description: Can't make sessions work Hi! My problem is that I can't make sessions work. I have the following script: <? session_start(); session_register('count'); $count++; echo "<P>You have been here $count times. Thanks!</P>"; ?> And php returns: Warning: open(/tmp/sess_e1aa51f9a5c92f30bc18b2ae9eb153e4, O_RDWR) failed: m (2) in Unknown on line 0 /tmp is created and read/write/execute/script are all allowed. After 3 times of refreshing the page php reports: Warning: Nesting level too deep - recursive dependency? in Unknown on line 0 And it keeps on reporting this untill I stop the hole IIS service and start it again. I am using the ISAPI module of php. What can be the problem? Please help me if you can reproduce the failure or not and tell me about all the possible solutions. Thanks, David Szilagyi
