MinimServer stopped on Synology NAS

[Bronx54]

Hi

I have a Synology DS115j NAS drive with minim server running on it, this ha been working well for over two years, I now have started having a recurring problem which may have started after some updates to the Synology (I did not instigate these).

When I go to my streamer first time on a day it does not see MinimServer, I then go to the Synology and find that minim server has stopped. It restarts ok and everything runs normally. I can stop using the system and later come back to it and all works fine. Then the following day I go to the system and find MinimServer has again stopped.

The NAS drive does an automatic back up at 3.00am in the morning and this is the only thing I am aware of happening overnight which is when MinimServer appears to stop running.

Current version of MinimServer: 08.5.3 (update 128)

NAS drive Synology DS115j, backed up using hyper vault to a DS216j
DSM Version: DSM 6.2.2-24922

When you login to the NAS in the morning and MinimServer has stopped, please look at the minimserver.log file in the MinimServer/appData folder and copy and paste the last 50 lines of this file to a post here. You need to do this before restarting MinimServer as this overwrites the log information. Also, are there are any files in this folder with names containing "minimserver-crash" or "hserr"?

Ok here we go.

ohNet fatal error: Unhandled exception NetworkAddressInUse at OpenHome/Network.cpp:324 in thread AdapterChange

Thanks for this information. This problem is caused by a flaw in ohNet (used by MinimServer) when the NAS is used as a VPN client in certain cases. Please can you post full details of your VPN setup, including which VPN service the NAS is accessing.

[Bronx54]

Sorry not sure how to get this information, not very savvy with networks, my NAS drive connects to an Apple airport extreme router via a Linksys 8 port gigabit switch. Internet connection is through a Draytek Vigor 130 modem.

I have looked through the DS115j settings and parameters and cannot find any reference to VPN settings, I have also looked at the Airport Extreme and cannot see any reference to VPN settings.

[simoncn]

In DSM, open Control Panel, then select Network, then select the Network Interface tab. Do you see anything there that says VPN?

[Bronx54]

Hi I cannot see anything with VPN listed the below is what is shown on the screen you suggested.

The control panel, Network Interface has the following.

LAN
Connected

Use DHCP Yes
IP address 10.0.1.19
Subnet mask 255.255.255.0
IPv6 address fe80::211:32ff:fe40:daa9/64
Network Status 1000 Mbps, Full duplex, MTU 1500

PPPoE
Disconnected

IPv6 Tunneling
Disconnected

Thanks for this. To investigate the problem further, I will need you to produce a debug log and send it to me. I will send you a PM with instructions for doing this, probably tomorrow. Thanks very much for your help with investigating the cause of this problem.

[squarefrog]

I'm having this issue as well. If there is anything I can do to help, please let me know.

[simoncn]

Do you have a VPN client running on your NAS (see above posts for how to check this)?
