Re: [SOAP] Frequent crashes in multithreaded webserver since new WSDLcaching code in ext/soap

Dmitry, Please don't commit things to the code from under me.. If you read the comments, you would see that I fixed the serious crash that was occuring and was working on that fixing the other one. -Andrei On Apr 17, 2006, at 6:19 AM, Dmitry Stogov wrote:

Hi Uwe, I just fixed sevral bugs in new code and re-enabled disk cache. Could you test CVS version (or snapshot)? Thanks. Dmitry.

This webserver is multithreaded so your new WSDL caching code in ext/soap should work great. But it doesn't. The first call to a php script that uses SoapClient works correct (everytime). Further requests to the same script crash the webserver with SIGSERV, SIGBUS, etc. Here are some different the crashs I have seen yesterday. The problem is that it happens at totally different locations, most times there is not even a core dump available that can be analyzed (stack is corrupt so no dump availabe): [13/Apr/2006:16:49:35] info (25237): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:18:38:15] info ( 8381): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:18:38:15] info ( 8381): CORE3262: Crash occurred in function master_to_xml from module /pangaea/webserver61/bin/libphp5.so [13/Apr/2006:18:44:03] info (11702): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:18:44:03] info (11702): CORE3262: Crash occurred in function encode_reset_ns from module /pangaea/webserver61/bin/libphp5.so [13/Apr/2006:19:02:17] info (12182): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:19:02:17] info (12182): CORE3262: Crash occurred in function strcmp from module /usr/lib/libc.so.1 [13/Apr/2006:20:02:13] info ( 1965): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:20:02:13] info ( 1965): CORE3262: Crash occurred in function encode_reset_ns from module /pangaea/webserver61/bin/libphp5.so [13/Apr/2006:20:04:37] info ( 3221): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:20:04:37] info ( 3221): CORE3262: Crash occurred in function whiteSpace_collapse from module /pangaea/webserver61/bin/libphp5.so [13/Apr/2006:20:13:10] info ( 5916): CORE3261: Crash occurred in NSAPI SAF php5_execute [13/Apr/2006:20:13:10] info ( 5916): CORE3262: Crash occurred in function whiteSpace_collapse from module /pangaea/webserver61/bin/libphp5.so When I disable soap.wsdl-cache completely, everything works again without any crash. I have seen that wirth the new code no longer /tmp/wsdl-XXXXX files are generated. Is there a possibility to switch to the older file-based caching code? For eaxample as enumeration in the wsdl-cache php.ini configuration option? Is there any other possibility to disable the wsdl cache code without undoing a lot of soap patches? I want to update the webserver because of security reasons to latest snapshot. Do you have similar problems with other webservers that are multithreaded? Sorry that I cannot give more helpful information (the crashes are totally different and the corefiles are mostly useless). ----- Uwe Schindler thetaphi@php.net - http://www.php.net NSAPI SAPI developer Bremen, Germany
