Hello! If i use DSO as php handler my messages.log is flooded with error messages like this: kernel: [] grsec: From Segmentation fault occurred at ... in /usr/sbin/httpd ... if i change to CGI as php handler for example, error messages are gone. Hope somebody can help.

  Have you checked for answers on the grsec forums? forums.grsecurity.net/viewforum.php?f=3

  Yes, i checked and read through a lot of similar topics, but found no answer to my problem... Did also core-dump to debug the problem, but can't make anything out of the log

  Hello, The grsec kernel is not officially supported so we generally ask that you try temporarily running a stock kernel to see if you can reproduce the issue. Feel free to open a support ticket using the link in my signature if you'd like us to take a closer look. Thank you.

  Thank you for the help! Just for your information: i have another server with grsec and that has no problem with cpanel(php handler: suphp) Anyway now i changed kernel to stock kernel and problem is gone, guess i have to stay with it, so to anyone in the future: Currently cpanel(php handler: DSO) does not work well with grsecurity linux kernel, so change to stock. I'm glad the error is gone at least :)
