 process will not die Hello, under special situations I have to kill a process on a HP-UX 11.11 server (PA-RISC, all patches installed). In some situations, the process will not die. Even "kill -9" doesn't work. Is this behavior correct? I always thought that a SIGKILL will work under any conditions. BTW: The process is a Sybase Adaptive Server Enterprise 12.5.0 on a two processor A-Class 500 server with two database engines. I want to kill both dataserver processes, but none of them is killable. So I have to reboot the machine which takes about 5 minutes downtime :-( Regards, Elmar -- __________________________________________________ ___________________ | | | knipp | Knipp Medien und Kommunikation GmbH ------- Technologiepark Martin-Schmeisser-Weg 9 44227 Dortmund Germany Fon: +49 231 9703-0 Elmar.Knipp@IHATESPAMknipp.de Fax: +49 231 9703-200      |

One can not really kill any process. One can only ask (all but 9) or tell (9) a process to commit suicide. This is a small but important distinction. In order to commit suicide, a process has to run. When, for example, a process is stuck in I/O suspension, it does not run and hence it can not commit suicide. You can also not kill a zombie/defunct process, but sometimes you can make it go away (see zombie in glossary(9)). [deleted] |
