Your listener is not stopping.
It fails to create server process for the new client connection.
Pay attention to this message:
TNS-12500: TNS:listener failed to start a dedicated server process
which usually means there isn't enough resources on the machine (i.e.
memory), or oracle reached max # of allowed processes, defined by init
parameter.

Hi Again .
When the dbase hangs the listener.log file shows the following errors :
TNS-12547: TNS:lost contact
TNS-12560: TNS:protocol adapter error
TNS-00517: Lost contact
32-bit Windows Error: 54: Unknown error
TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12560: TNS:protocol adapter error
After i serached about window error 54 i found it is a network error
,also the error may be from swap space and virtual memory ( number of
semaphores...) i will increase these and monitor performace event log.
Oracle version 9.2.0.4.0 on window nt 2000 .
Can any of you add another suggestions ?

What version of Oracle is this? (and what Win version)?
Put the listener in debug mode (lsnrctl then trace debug , or
modify the listener.ora )

Thanks Ghassan,
I checked the listener.log it shows every thing normal.
however when the problem happens i check tns-service in
contral panel->services i find sid service is running however the
listner service is not running so i restart the server and so on... is
the listener becoming tired when i have many connectins !
the system adminstrator cannot find the meaning of the
error " local agent reponse " in the system event , how shall i proceed
in the investigation.

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.

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.
