hi ! No , i do not think so ! the server is 3G of Ram ! . I have set listener trace to admin and waiting for the dbase to stop. However i have found these errors in the system event : -local response agent event id :11 " critical error " -service control manager event id 7031 . the administrator failed to explain to me what these errors are ,also we are running DHCP ,does it have something with the listenter ?

Ghassan Salem <salem.ghassan@xxxxxxxxx> wrote: Walid, what do you mean by 'listener is stopping'? if you do a 'ps -ef|grep tns', you see no tns program running? if that is the case, look at the listener.log (in oh/network/log) to see if there is any error message there. rgds On 11/18/06, walid alkaakati < walid_alkaakati@xxxxxxxxx> wrote: Hi list , I need your help on this urgent issue . Each day iam facing a problem , the applicaton is freezing and all my users (150) can not do any thing and you cannot do any new connections , some times this is accompanied by message (" can ot open dedicated server process...."), when i checked the services i found that listener is stopped automatically ! I wonder why it is stopping IS it that i have to add new listener or what ? Net work problems ? how i verify that it is a network problem ? the alert .log do not show anything , the window event shows " local agent error " where i shall start? Wating your help.
