#48813 [NEW]: used ob_start() and CPU usage become 100%
From: manju_kalita at infosys dot com
Operating system: Linux
PHP version: 5.3.0
PHP Bug Type: *General Issues
Bug description: used ob_start() and CPU usage become 100%
Description:
------------
I have used:
ob_start(); #at the starting of the scipt
ob_flush();
ob_end_clean(); # at the end of the script
everything working fine. But when I go to next page and do a IE back,
sometime the CPU utilization reached 100% in client system and the IE got
crashed.sometime its work perfectly.
In any other script, we are not using ob_start() or ob_flush().
Please let me know how can we manage the memory utilization to prevent
this issue.
Expected result:
----------------
IE back sud work and CPU utilization should not reach so high.
