# Can’t scan since update

 *  Resolved [wpelvis](https://wordpress.org/support/users/wpelvis/)
 * (@wpelvis)
 * [9 years ago](https://wordpress.org/support/topic/cant-scan-since/)
 * Unable to complete a scan since the 6.3.7 update.
    I updated to 6.3.8 and i do
   not get fatal errors, however Wordfence can not finish a scan. I have followed
   all the instructions on [https://docs.wordfence.com/en/Scan_time_limit](https://docs.wordfence.com/en/Scan_time_limit)
   but it does not make a difference.
 * The scan doesn’t get past
    `Comparing core WordPress files against originals 
   in repository` and the error is `Scan terminated with error: The scan time limit
   of 3 hours has been exceeded and the scan will be terminated. This limit can 
   be customized on the options page.`
 * Is there anything else I can do?
    thanks

 * Hi [@wpelvis](https://wordpress.org/support/users/wpelvis/),
 * Apologies for the delayed response.
 * Although it isn’t directly related to Wordfence, the error displayed in the log
 * `ob_end_flush() [ref.outcontrol]: failed to delete buffer zlib output compression(
   8) File: /home/savethemale/public_html/wp-includes/functions.php Line: 3720`
 * points to a part of the WordPress code that should apply when the site is using
   _PHP version 5.2_.
 * In case you’re running that specific version of PHP, this would also explain 
   the difficulties Wordfence has to perform the scan in a timely manner. (see [here](https://docs.wordfence.com/en/Wordfence_system_requirements)
   Wordfence requirements)
 * If you’re using a more recent version, please note that the latest Wordfence 
   update (6.3.10) includes an improvement of the overall memory usage and peak 
   memory usage for the scanner, which appears to be high in your case
 * `Wordfence used 120.19MB of memory for scan. Server peak memory usage was: 254.83MB`
 * Please upgrade PHP and/or Wordfence and let me know if the scan is able to run
   to completion.
