Hello,

today in the morning I was checking our Piwik and had to read the following two messages.

WARNING: /var/www/html/vendor/doctrine/cache/lib/Doctrine/Common/Cache/FileCache.php(251): Notice - tempnam(): file created in the system’s temporary directory - Piwik 2.17.1 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)

WARNING: /var/www/html/vendor/doctrine/cache/lib/Doctrine/Common/Cache/FileCache.php(254): Warning - file_put_contents(): Filename cannot be empty - Piwik 2.17.1 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)

As it states I report this to this forum and fyi: I couldn’t find it inside the forum.

Best regards

Today after Upgrading for A/B Testing Plugin I received the following message while archiving:

/var/www/html/core/CliMulti/Process.php(248): Warning - shell_exec(): Unable to execute ‘ps ex 2>/dev/null | awk ‘! /defunct/ {print $1}’ 2>/dev/null’ - Piwik 3.2.0 - Please report this message in the Piwik forums:

Hello all,

this error appears when there is less space on your harddrive. For me it was enough to clear my log files to remain some space.

After that action the message was gone.

Hope to help.

Regards, Marcel
