>From what I remember seeing somewhere, the 3+ is actually different hardware whereas the 3 and the 3i share common hardware, so they would need different firmware from the 3+.

The problem with the SunRay3 (not +) clients seems to be that some specific network traffic seems to trigger that DTU reset. Here I have already catched a network snoop for the support request and sent it to Oracle support. Lets hope they can investigate which network packages are triggering these resets and that they can come up with some updated firmwares. The other option is that this is actually a hardware bug of the network hardware. However, it is definitely not a bug/problem within the SRS software but a specific problem with the SunRay3 hardware/firmware somehow. But the case that the 3+ clients are not affected is a bit strange to me and somehow points to a more severe problem of the SunRay3 DTU hardware. best regards, jens [email protected] schrieb: > Hi , It seems to be affecting Sunray3 and not sunray2 nore sunray3+ > Will have to do some more validation tomorrow. > > I have established that the users uttsc process does not crash > but survives > the DTU disconnect ( reboot ? ) > > The process that reports the disconnect is the Authd java process. > probably saying that the DTU has dissapeared.
