Jerry and Phil are investigating this. In the meantime, Teknowledge will try using a potentially unreliable workaround to recover from the 0915.'

' The origianl problem was Dlion crashed at MP 915 during Install lisp.sysout. This was due to a an error raised from Pilot''s Stream interface that the tool failed to catch and was fixed quickly . Then three different symptoms were observed during tracking the problem in El Segundo, they were': 1) "Connection rejected by remote host, while connected to Taos", 2) "Connection timed out, while connected to Taos", and 3) "Opening connection to Taos... and "Connection timed out".' ' ' 1.) "Connection rejected by remote host, while connected to Taos"' ' This is a logic error in the InstallLispTool in determining the termination of data transfer. The tool was using the file size (byte count) to control the termination of end of data transfer. It turns out this file size is not an accurate data count but an estimate. The tool was than waiting for more data to come even when Vax has sent over an "end of message" packet, thus it timed out. The correct way to terminate is to use the "end of stream" completion code returned by Stream interface. ' ' How did this works previously with DEI software and with SDD''s IFS are beyond my understanding. ' ' ' 2). "Connection timed out, while connected to Taos" ' ' This one is a bug in the DEI 6.0. As I understood from Don Vale is that the DEI uses the data packets when in "store" or "retrieve" to re-set their connection timer, currently set at 5 minutes. DEI 6.0 neglected to use "ack" packet to reset their connection timer, in the retrieve case there are no data packets as in store, and for very large files (especially takes more than 5 minutes to retrieve) the connection got broken. DEI 6.1 has a quick patch in extending the timer to 10 minutes. (see attached Bill''s message).' ' ' 3) "Opening connection to Taos... and "Connection timed out"' ' This symptom showed up many times in Wednesday. Don Vale collected tha packets exchanged between Dlion and Vax, and believed Pilot is not hanling the RFC properly at a certain state. Since this problem did not show up after we put in out patches, I presume it is not a problem any more. If it shows up again, I will submit an AR against System Software together with the trace Don collected.'
