if each dig request needs over 4 seconds , also NET::DNS used by ASSP have the same big delay ; this delay was showing near to 100% cpu on info stat page plus seconds of timeout sending email .Don't ask me why , but it's so.
I do not know what technique uses Frtiz to show cpu usage on "info stat" page however using NET::DNS filters "info stat page" was reporting near 100% cpu. However note that using ps aux | grep assp.pl was returning a cpu usage of about 5% !!! . On linux I never seen the same value between "ps aux | grep assp.pl" and info stat page , never. However the near to 100% signal on info stat page (with few smtp connections) and the time out problems sending email , told me that there was a problem . I tried to disable all filtesr and then enable one by one . I noticed that the problem (100% cpu and time out problems) was stopping turning to 0 all assp filters which were using NET::DNS . I tried to downgrade and upgrade NET::DNS .Nothing . Then Fritz wrote that was a DNS iussue ,so I executed several dig domain.com on this server , and I found that the answer query time was really big (over 4 seconds for each query while on another server with the same "dig domain" was returning queries under 0.5 sec) . So I agree that it's DNS iusse . Bye Graziano > On Thu, 2007-10-04 at 11:36 -0600, Graziano wrote: > >> DNS, correct !
