I read a message from the archives that describes nearly our exact problem
that has begun to appear after 11i was installed on our server. File
access has become slow and unreliable, especially under high loads. As a
matter of fact, I had a logon script running a series of echo -- it was
executing them at about 1 line every 2 seconds. The way we "solved"
the
problem was moving the Samba tree to a high-speed array; now it's flaky,
but faster at being flaky so it is not as noticeable. However, I'd
obviously like to correct the problem. The last gentleman who had this
problem never received a response (that was in 2001) -- let's see if
anyone has had any luck since.
I will include what I have determined to be relevant log entries -- though
I could be mistaken. Here is one PC's logon process:

...what is it doing looking for moricons.dll in the first place? I see
this all over my logs -- it looks for things like moricons.dll and
rundll32.dll on the Samba server in the first place?
The other one I see is that it appears to attempt to read files over and
over. Here is an example:
