[Miguel, I'm coping you since I think that you're SSL problems from
14Feb2009 might be related to this.]

Is there any specific value/behavior on the adaptor info page that
needs to be checked/monitored?
I went back to Terry's detail post and noticed that the logs show'd
that the adaptor is marking the instance as dead. You should be able
to see that on the WOAdaptorInfo page however it will only be that way
for 10 seconds so you have to be quick.
Also, I noticed this message:
Error: sendBuffers(): send error: Invalid argument
"Invalid argument" corresponds to errno 22 - EINVAL
That error is being thrown by the sendmsg() system call, called by
sendBuffers().
I'm looking at: WebObjects/Source/Adaptors/Adaptor/nbsocket.c
The docs for sendmsg() are here:
http://docs.sun.com/app/docs/doc/816-5170/send-3socket?a=view
There are 3 cases documented to return EINVAL
1) there are no buffers
2) one of the buffers is of negative size
3) the total size of all buffers is greater then ssize_t (seems be
defined as long on Solaris 10)
The adaptor checks for case 1, and case 2 seems unlikely although it
might occur with a weird header.
Case 3 also seems unlikely since the adaptor specifically switches to
streaming to handle large requests.
Also, I noticed that the log shows that the failure occurs on the 8th
R/R loop!
What was the user doing then? Some kind of submission or upload
perhaps?
(Yes, I noticed that there's no notice of streaming in the log, I'm
just checking. ;-)
If that still doesn't point to what the error is then I'd modify the
adaptor to dump the buffers when this condition occurs so that we can
nail down what's happening in this case.
Anyway, hope that helps!
Also, I'm available to look into this in more detail if you can't
figure out what's going on. ;-)
