I use monit for monitoring all services on my system and recently I add Apache2 ( 2.4 ) to it. Just to mention I use Debian 8 on ARM system.I use init.d and not systemd.



After I add Apache and config it use "mpm_prefork" module , and remove many modules from "enabled" modules, to get it more light-weight.



All these not help me and I still get Apache2 restarts every minutes.



Did anyone have such experience and troubleshoot such problem ?

  • As @RubberStamp has implied, we need more and detailed information to help. How do you know apache is restarting every minute -- what log entries indicate this? Do they include any error messages? Maybe consider reading this: unix.stackexchange.com/help/how-to-ask

  • the pid location changes between versions. Are you pointing to the wrong apache.pid location in monit?
    – Rui F Ribeiro
    Oct 28 '17 at 21:48










  • Are you using python? If not, try disabling the wsgi module and see if the problem goes away... a2dismod wsgi ... You may also want to try switching to the itk module instead: Apache 2 ITK MPM it's available on Debian 8 ... and the mpm_prefork module seems to have been removed from Debian 9, in favor of itk

  • As @RubberStamp has implied, we need more and detailed information to help. How do you know apache is restarting every minute -- what log entries indicate this? Do they include any error messages? Maybe consider reading this: unix.stackexchange.com/help/how-to-ask

  • the pid location changes between versions. Are you pointing to the wrong apache.pid location in monit?

  • Are you using python? If not, try disabling the wsgi module and see if the problem goes away... a2dismod wsgi ... You may also want to try switching to the itk module instead: Apache 2 ITK MPM it's available on Debian 8 ... and the mpm_prefork module seems to have been removed from Debian 9, in favor of itk

I use monit for monitoring all services on my system and recently I add Apache2 ( 2.4 ) to it. Just to mention I use Debian 8 on ARM system.I use init.d and not systemd.



After I add Apache and config it use "mpm_prefork" module , and remove many modules from "enabled" modules, to get it more light-weight.



All these not help me and I still get Apache2 restarts every minutes.



Did anyone have such experience and troubleshoot such problem ?

  • As @RubberStamp has implied, we need more and detailed information to help. How do you know apache is restarting every minute -- what log entries indicate this? Do they include any error messages? Maybe consider reading this: unix.stackexchange.com/help/how-to-ask

  • the pid location changes between versions. Are you pointing to the wrong apache.pid location in monit?

  • Are you using python? If not, try disabling the wsgi module and see if the problem goes away... a2dismod wsgi ... You may also want to try switching to the itk module instead: Apache 2 ITK MPM it's available on Debian 8 ... and the mpm_prefork module seems to have been removed from Debian 9, in favor of itk

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
