Previous Comments: ------------------------------------------------------------------------ [2021-01-06 14:25:45] cmb@php.net Is that still an issue with any of the actively supported PHP versions[1]? [1] <https://www.php.net/supported-versions.php> ------------------------------------------------------------------------ [2015-01-19 09:19:36] fs at gigacodes dot de It seems to only be somewhat time-based. I tried calling the script once per second and it occured after 15min and when i called every 30 sec it was the same. The problem does not occur on cli! I enclosed the script in a for loop and let it run for 2h without problems. Same thing when it's a for loop in the fpm script. The problem only seems to occur when using separate requests to fpm. ------------------------------------------------------------------------ [2015-01-16 21:06:13] danack@php.net Do you have any idea if it's just time based, or is it related to the number of requests made? And have you ever seen the same behaviour when running a test from the CLI? ------------------------------------------------------------------------ [2015-01-15 15:50:56] fs at gigacodes dot de Description: ------------ the xmlreader open call will function correctly for about 15-30minutes after starting php-fpm. After that it will not even try to access the remote url and fail with an "failed to load external entity" error. In an strace i can sometimes see that it will do a 'stat' system call on the url (which is quite weird) but will not even try to do anything else. When i restart php-fpm it will work immediately again for about 30 min. The wsdl file in the test is just a public weather api i used for reproducing. We initially encountered this problem within SOAPClient but could track it down to XMLReader. System is a CentOS 7 with all updates (as of 15.01.15) and a php-5.5.20 compiled with: ./configure --prefix=/home/php-${version} --with-mysql --with-gd --with-curl --with-zlib --with-jpeg-dir=/usr/lib/ --with-iconv --with-pdo-mysql=mysqlnd --with-openssl --enable-mbstring --with-mysqli --with-gettext --enable-sockets --with-mcrypt --with-freetype-dir=/usr --enable-soap --with-xsl --enable-opcache --with-oci8=instantclient,/usr/lib/oracle/12.1/client64/lib --enable-sysvsem --enable-fpm --enable-pcntl --enable-bcmath --with-gmp Test script: --------------- <?php function loadXML() { try { $xml = new XMLReader(); $xml->open("http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"); $xml->setParserProperty(XMLReader::VALIDATE, true); var_dump($xml->isValid()) . "\n"; return null; } catch (Exception $e) { return $e; } } $start = new DateTime(); echo "Start: ". $start->format('Y-m-d H:i:s') ."\n"; $e = loadXML(); var_dump($e); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68838&edit=1
