I would especially agree for linux with heavy I/O... Which is pretty much everything I've got... :) Sent via BlackBerry from T-Mobile

Regardless of RAC or no RAC this error is quite common in 10gr2 databases specially if it is remote database server. I have also seen this behavior on Linux server when server is quite busy for various reasons. SQLNET.INBOUND_CONNECT_TIMEOUT settings is now 10 seconds by default instead of 60 seconds in previous versions (if I remember correctly).

I would never be one to point fingers- I'm a DBA and do not understand the network infrastructure as well as the Network admin, but as a DBA, I do have to deal with the errors and the database is always guilty until proven innocent. We will and do get these errors unless I put in the following parameters into my sqlnet.ora file:
SQLNET.INBOUND_CONNECT_TIMEOUT = 300 SQLNET.SEND_TIMEOUT = 300 SQLNET.RECV_TIMEOUT = 300
Cycle the listener and these errors disappear. Now-do I think there is most likely something amiss that I require this in my sqlnet file? Yes, most definitely.. Do I have the time or skills to figure it out? Very questionable... :)

We set the INBOUND CONNECTION TIMEOUT=0 in RAC AIX environments, but

Anyone know why this would be happening?
