I have also problems with archive.php since Piwik 2.1.0.
I am running the process on Synology NAS and thisi is the error message :
ps: invalid option – 'e’
BusyBox v1.16.1 (2014-03-06 14:29:34 CST) multi-call binary.
Report process status

Error in the last Piwik archive.php run:
The Piwik URL Sign in - Piwik does not seem to be pointing to a Piwik server. Response was ‘’.
Here is the full errors output:
Piwik is installed at: Sign in - Piwik
Running Piwik 2.1.1-b10 as Super User: spocky
ERROR: Got invalid response from API request: http://piwik.lejardindeschimeres.org/index.php?module=API&method=API.getDefaultMetricTranslations&format=original&serialize=1&trigger=archivephp. The response was empty. This usually means a server error. This solution to this error is generally to increase the value of ‘memory_limit’ in your php.ini file. Please check your Web server Error Log file for more details.
The problem seems coming from the fact that the commande “ps -e” is used somewhere but under Synology the “e” option is not valid. Would it be possible to help me to locate where this command is used in the script in order to get rid-off the “e” option ?
