Home -> Community -> Mailing Lists -> Oracle-L -> Re: TNS-12518: TNS:listener could not hand off client connection
Amit:
Sometime it may happens if tcp/ip QUEUESIZE is small on OS level. I am not sure about linux OS parameter, which probably you can get from your system administrator.
For other OS, these parameters are :
Sun Solaris: tcp_conn_req_max_q (default 128)
HP-UX: tcp_conn_req_max (default 20)
HP Tru64: somaxconn (default 1024)
Thanks
