#41943 [Opn->Fbk]: Soap Call causes CPU to go 100%

ID: 41943 Updated by: tony2001@php.net Reported By: simon at connexon dot com -Status: Open +Status: Feedback Bug Type: Performance problem Operating System: Windows Server 2003 PHP Version: 5.2.3 New Comment: Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report.

Our average waiting time is 4 seconds. A soap call once in a while is ok, because it doesn't take too much CPU overall. But we noticed that the more we grow, the more CPU it takes, to a point where we reach often 100% CPU if we do a loop of soap calls. (All that caused by the waiting time of the soap call!!!). Reproduce code: --------------- x Expected result: ---------------- Would it be possible that PHP goes into an idle mode when it waits for a soap response instead of taking all the CPU ressources? Actual result: -------------- CPU goes crazy when we do too many soap calls in a row (we can do maximum of 4 soap calls at once, else it would overload the server). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41943&edit=1
