[DSM - Sorry, the page you are looking for is not found]

I have been trying to get my EX-490 up and running for some time now. Have replaced all the disks with up-to-date ones and am trying to install DSM 6.1.x.

 

But after running a few days it starts to collaps with the invalid ELF header. Copying and replacing the necessary files to /lib fixes it. But what causes this?

 

Only packages i'm installing default after a reinstall are photo station and video station.

 

Anyone?

 

Edit 1: hmm, could it have anything to do with this? https://xpenology.com/forum/announcement/2-dsm-serial-number-please-read/ I did see some sn warnings regaring video station

[DSM 6.1.x Loader]

Hi all,

 

I tried fresh installing 6.1.3 on my EX490 (first experience.) The installation runs fine and all is well until after a few days dsm crashes and I'm shown the message "Sorry, the page you are looking for is not found". 

 

- SSH acces works

- DSM doesn't work

- Photostation doesn't work etc.

 

/var/log/synoservice.log shows: "2017-08-28T12:28:41+02:00 xxxxx synoservice: service_start.c:180 synoservice: [pkgctl-PhotoStation] start failed.[0x0000 (null):0]"

I can probably reinstall (did that 2 times) but would like a stable system. Do I need to downgrade or is this fixable?
