We are having some issue with the Piwik archiving process, after upgrading to 1.7.1 from 1.6 we are occasionally getting the following error:
PHP Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 80 bytes) in /var/www/html/piwik/core/DataTable/Manager.php on line 76
The archive script is run every two hours and as far as I can see this error only occurs on the first run of the day.
We are running Piwik with on a CentOS 6.2 box with:
2GB physical memory / 1GB swap.
I can’t see any open bug reports related to error messages originating from Manager.php but there is a bug report for archiving memory leaks Archiving Memory exhausted error - Archiving memory leaks · Issue #766 · matomo-org/matomo · GitHub. Is this a known issue and is there a work around?
