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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48813&edit=1
