Visitor Log - memory or max execution script error only for a specific user

Hello, since some days we have a problem with a piwik user when clicking on Visitor Log. The error occurs only for this user. Other users have not the problem.
The error is: Oops… there was a problem during the request. Maybe the server had a temporary issue …
In the apache error logs we saw first that it was a memory problem:
PHP Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 80 bytes) in /var/www/html/piwik/libs/Zend/Db/Statement/Mysqli.php on line 235
So we changed the memory_limit value in the php.ini file and restarted the server. But it didn’t help, after that it was a script time execution error:
PHP Fatal error: Maximum execution time of 30 seconds exceeded in /var/www/html/piwik/core/Date.php on line 301
Always when using same account, no problem for other accounts.
Do you know what could be the reason and how could we solve the issue for the account having the problem ?

Hi, what about deleting the user and creating it again?
