[Throwaway]

We have pretty big dynaforms being used but for some reason when they're being saved/submitted. It throws this error.

Code: Select all

No database selected [Native Error: MySQL server has gone away]

The issue is that we've modified the timeout and increased the max packet size to 500M, and those worked momentarily. Then I got this error on another case.

Code: Select all

Unable to execute UPDATE statement. [wrapped: Could not execute update [Native Error: Got a packet bigger than 'max_allowed_packet' bytes]

PM shows 500M as the packet size, is it reset or hardcoded in ProcessMaker? I don't see any issues in sysGeneric.php

You can check what the current settings are by creating a trigger in your process with this code:

Code: Select all

$aSettings = ini_get_all();
print "<pre>";
print_r($aSettings);
die; 

See: http://php.net/manual/en/function.ini-get-all.php

You probably have to increase max_allowed_packet, max_post_size and max_input_vars.
