Hello, I had to reboot the machine and ever since it has not reoccured although it had happend a number of times before. Wonder if it might be related to powerlan for I had to reboot these as well. Anyway just for completeness sake here are the answers: Am 22.02.2016 um 05:54 schrieb Steve French: > > Also would be useful to know if this fails on more recent kernel > I'm using 3.18.25 as this was (at that time) a longterm kernel version. I've recently upgraded to 3.18.36 (currently one of the longterm kernels)? A newer kernel (4.6.3) had some graphics issues so it's not usable for me. > On Feb 21, 2016 22:37, "Shirish Pargaonkar" > <shirishpargaonkar@xxxxxxxxx <mailto:shirishpargaonkar@xxxxxxxxx>> wrote: > > There may be some kind of deadlock, that is why soft mount option is > not responding, > otherwise you would seen something like "host is down" > All of the shares show DISCONNECTED in file DebugData. > Can you use crash utility and see the stack trace of the ls > command that hangs? > What if you mounted from just one share/server (1.1.1.22 e.g.), do you > see the same problem? > I don't have crash installed and am somewhat reluctant as it has quite a footprint. I assumed the call trace in messages to be a stack trace. Can I get more useful information by attaching with gdb? What should I be looking for? I usually work with both of them. As the hang only occurs after some time I can try to only mount the second nas when needing it and unmounting it later. Why do you think it might have an impact? Thanks a lot for your answers and I'm happy it has vanished at least for quite some time now.
