Severity: Warning --> preg_replace() [function.preg-replace]: Compilation failed: regular expression is too large at offset 36332
fuel\codeigniter\core\Security.php 641

Seems the issue come from CI, but are there any method to solve this error?
This error occurred when i save in the admin panel.

Thanks.

This looks to be something the xss_clean function is doing. What module are you saving from? If it is your own module, the xss_clean function is used by default for modules but can be overwritten in your MY_fuel_modules.php by adding the following to your for the particular module you are having trouble with:
... 'sanitize_input' => array('template','php'), ...

It is a simple module for a model named.

below is my setting in MY_fuel_modules.php.
$config['modules']['paper'] = array( 'sanitize_input' => array('template','php'), 'default_order' => 'desc', 'icon_class' => 'ico_research', );

It is added after your suggsstion, but still not work
'sanitize_input' => array('template','php'),

When i save the model in admin, i lost the "text" in the textarea.
And then i found the error message in the log file
Compilation failed: regular expression is too large at offset 36332 Line 641
Security.php Line 641 $str = preg_replace('/(<?)(\/?[^><]+?)([^A-Za-z<>\-])(.*?)('.implode('|', $attribs).')(.*?)([\s><]?)([><]*)/i', '$1$2 $4$6$7$8', $str, -1, $count);

The error occurred only if the field have too many text.

Perhaps adjusting this setting may help in your php.ini:
