Hello, we are a gruop of students from The Catholic University from Chile (South America) who are working in a optimization proyect. We Coded the model and data with AMPL but we´re having trouble with the solver (our model is mixed nonlinear-binary) so we used the kestrel solver to acces de NEOS and use the Bonmin solver, a couple of hours ago all was working perfectly but now we´re getting errors when accesing the kestrel solver: Traceback (most recent call last): File "kestrel.py", line 258, in ? File "kestrel.py", line 129, in formXML File "kestrel.py", line 88, in getSolverName File "xmlrpclib.pyc", line 1096, in __call__ File "xmlrpclib.pyc", line 1383, in __request File "xmlrpclib.pyc", line 1147, in request File "xmlrpclib.pyc", line 1286, in _parse_response File "xmlrpclib.pyc", line 744, in close xmlrpclib.Fault: <Fault 1: "<type 'exceptions.IOError'>:[Errno 5] Input/output error"> exit code 255 <BREAK> We really need this proyect running so every help is apreciated, we think its a server error and info about the server´s state is apreciated.

Mayur, You may have to wait until the queue is shorter before submitting your job. If you expect your problem to run quickly (under 5 minutes) then you can add a priority option in the commands file: option kestrel_options "solver=XXX priority=short"; The queue reserves a few spaces for short jobs.

Kurt, I don't know why this is happening. Let me know if you are still having trouble, I can try moving the file to our ftp server.
