Client sqlplus SELECT + SPOOL knocks down server network
Date: Mon, 10 Mar 2008 04:51:00 -0700 (PDT)
I'm facing a strange problem on a 10.2.0.3 Oracle on Oracle Enterprise Linux 5 server.
This morning someone was issuing a SELECT from a windows client via ODBC and suddenly all the server communications broke down: even no ping from or to that server worked.
Tried stop&start network but no avail. The server appears to be dead at communications until reboot.
So I tried to repeat the SELECT from sqlplus on a windows client to a OS file with SPOOL and all the communications on the server are gone once again. Ping only answers to 127.0.0.1 or its own IP address, and Linux is telling me that the network card is OK. Stop&start network didn't fix the problem either.
Client sqlnet.log shows:
Fatal NI connect error 12170.

Tns error struct:

TNS-00505: Message 505 not found; No message file for product=NETWORK, facility=TNS
nt secondary err code: 60
nt OS err code: 0
Client address: <unknown>
The select is a two column (varchar2(9), char(1)) select of 11 million rows aprox.
Could anybody tell me where to search next? (I didn't find anything at metalink).
