Description:
------------
recently our users have been seeing the following error occur frequently but seemingly randomly when using our web application:

fatal error: Maximum execution time of 130 seconds exceeded in xyz.php line 132

the php file and line number are different each time the error occurs.  the error does not occur often, every few days or so. 

in our scripts we use the function:  set_time_limit(130);

I have spent much time researching our code, and now I would like to know if there is any new bug, or session related leak reported in php 4.3.8 which may be causing this problem. Each script we use always ends normally.  we are using php 4.3.8 on Solaris 9 with Apache 1.3.31.   the only change we made to php.ini file is we use register_globals on. we are using session_ids and session variables.  and we do wrap our output generating code between ob_start();  and ob_end_flush();
thanks.
