[Solved] Can't connect to DVBLink server anymore

Postby Oceanwaves » Tue Oct 17, 2017 7:09 am

Hello,

I rebooted my DS214play yesterday and since then I can't connect to my DVBLink server anymore. Each time I try to connect to it I get a message from Firefox saying that it can't connect to <ip of my ds214play>:39876.

I'm currently running DSM 6.1.3-15152 Update 7.

What I've done already:

- uninstalled DVBLink server
- rebooted the NAS
- installed DVBLink server 6.0.0 Build 14499
- rebooted the NAS

Still no connection to DVBLink server. I also don't see any service on port 39876:

In addition I see heavy disk activity on my DS214play but I have no idea what is causing this. System load is also fairly high:

Just checked the connection again and now it works. System is up for 58 minutes now. Don't know however how long it took for the port to become available.

I installed TVSource and TVAdviser and restored the configuration. After that I wasn't able to connect to DVBLink again for some minutes so I restarted my NAS again.

Surprisingly this time it took only 4 minutes until port 39876 became active.

3 minutes later: no ports available any more:

root@DiskStation:~# netstat -antop|grep dvb
root@DiskStation:~# uptime
09:18:47 up 7 min, 1 user, load average: 43.65, 35.25, 15.50

Process died:
root@DiskStation:~# ps -ef|grep -i [d]vb
root 12832 1 0 09:13 ? 00:00:00 ./dvblink_fwloader

There should also be a process "/var/packages/DVBLinkServer/target/dvblink_server" running :-(.

What's wrong???

Zipped log files with Info log level may help to find out what is wrong.

I'll try to get some, but the server dies after around 2 minutes, producing a 770 MB core file.

Log attached.

Procedure to get it:
- stop (crashed) package
- start package
- set log level to Info
- wait 2 minutes until server process crashes
- stop (crashed) package
- start package
- wait 2 minutes until server process crashes
- stop (crashed) package
- start package
- download log

Think it's time to migrate to my new DS918+ finally. I'm currently in the process of copying lots of files from backup to new destination. DVBLink is already installed on the DS918+ and - at least - doesn't crash.

Oops, have to correct me. DVBLink server also crashes on DS918+ (I copied DVBLink folder from DS214play, so may be there's a problem somewhere...)

Problem fixed.

Deleting the database (/DVBLink/database/dlrecorder.db) fixed the crashes on DS214play and DS918+.
