 * i suspect there’s a limit in the my.cfg i need to set/edit to eliminate this 
   error/warning, but just wanted to double check (and also to get a hint of what
   needs changing if that’s the case)
 * thanks
 * full logentry is as follows
 *     ```
       PHP Warning:  popen(cd '/..../wp-content/backups'; /usr/bin/mysqldump  --defaults-file=xxxxxxxxxxxx.tmp --max_allowed_packet=1M --quote-names --add-drop-table --skip-comments --skip-set-charset --allow-keywords --dump-date --extended-insert --where=option_name=\'siteurl\' --user='xxxxxxx' --host='localhost' xxxxxxxx 'wp_options' >xxxxxxxxxxxxxxxx.sqltest.tmp,r): Cannot allocate memory in /.../wp-content/plugins/updraftplus/class-updraftplus.php on line 745

 * Hi,
 * I could be wrong, but I think that’s something within the PHP/webserver setup
   rather than MySQL.
 * Best wishes,
    David
