I just had the same issues.
First it was “PHP Fatal error: Allowed memory size of 134217728 bytes exhausted”
fixed by upping php.ini memory_limit to 1024M
Then “PHP Fatal error: Maximum execution time of 120 seconds exceeded”
fixed by upping php.ini max_execution_time to 240.
That allows the first xhr request to return an array of 29k of media IDs (I’m sure that isn’t the best way to be doing it)
The next xhr request to “wpmc_scan_do” with 5 IDs resulted in “WordPress database error Got a packet bigger than ‘max_allowed_packet’ bytes for query INSERT INTO wp_options (option_name, option_value, autoload) VALUES (‘_transient_wpmc_galleries_images’,”
fixed by upping my.cnf max_allowed_packet to 16M
Now its finally chugging away, at about 1 image per 3 secs, and im expecting it to crash as soon as it encounters an image bigger than 16m. This will be fun.
Looks like the plugin could do with some optimizing.
