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 this bug report at https://bugs.php.net/bug.php?id=78585&edit=1
