Based on your post on the Parallels forums, you said Plesk was generating this error:
DEBUGGER DETECTED... Bye!
That is caused by a bug in Plesk. Plesk incorrectly "detects" you are running a debugger when you use a kernel (any kernel) that protects you from ptrace exploits. So, you just have to disable that protection in the ASL kernel:https://www.atomicorp.com/wiki/index.ph ... ..._Bye.21
Its not a bug in the kernel, its a bug in Plesk so its not something we can fix. This was reported to Parallels as a bug in their product a long time ago (over a year ago), but obviously they still havent fixed it. We recommend you add your voice to that growing list of users that have asked Parallels to fix this.
As a future tip, any time we are aware of some error like this we always document it in the FAQ:https://www.atomicorp.com/wiki/index.php/ASL_FAQ
So the first place to look is on our FAQ page, the odds are high that we have a solution already, even when its a bug in someone elses product.
