From: uozl3xwtrc25ri4u at mailban dot de Operating system: Arch Linux ARM PHP version: 7.3.9 Package: FPM related Bug Type: Bug Bug description:High CPU usage while syncing Nextcloud apps from phone Description: ------------ -Phone with Nextcloud News app -Raspberry Pi 3 Model B with Nextcloud, MariaDB, Lighttpd, php – all up to date -php-fpm version: 7.3.9 and 7.3.8 php-fpm 7.3.7 and earlier worked fine. Bug occurs on versions 7.3.8 and 7.3.9 only. Syncing with other apps brings up the same behavior. Nextcloud web access via browser seems normal. I initiate the syncing of the news app with my Nextcloud via http. Expected result: ---------------- Syncing takes 1-2 seconds. 1-3 threads utilize 10-20% CPU. Actual result: -------------- Syncing takes ca. 10-12 seconds. 1-3 threads utilize 50-100% CPU, at least one close to 100% in that time. -- Edit bug report at https://bugs.php.net/bug.php?id=78585&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=78585&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78585&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78585&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78585&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78585&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78585&r=support Expected behavior: https://bugs.php.net/fix.php?id=78585&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78585&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78585&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78585&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=78585&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=78585&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78585&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78585&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78585&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78585&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78585&r=mysqlcfg
