Since installing several torrent dockers (Deluge, Sonarr, Radarr and Jackett) I seem to get a lot of random connectivity problems both up and down. When running backups from other machines to unRAID I get warnings that the backup shares do not exist. I tried to recreate one time machine backup that had become corrupted but finally stopped the backup because it had only transferred 10GB of data in about 4 days. It's not unusual for me to have to refresh a webpage 3 or 4 times to connect to webui's for my torrent dockers. Today I can't connect to the Radarr page at all. The background loads but nothing else.

 

CPU load is low (<5% average). System Stats shows network activity has a few spikes up to about 500 kB/s but it looks to be averaging <100 kB/s (Deluge has about 50 torrents downloading right now ). This is over a 10/100 cat 6 ethernet.

 

I'm not much on networks. No idea where to start troubleshooting this. My motherboard does have an unused 10/100 nic. Maybe I need to start using it but that doesn't really seem like the issue to my uneducated thinking.

 

I've attached a diagnostics below. Any advice would be greatly appreciated. I'm sure there are details that I haven't provided. Feel free to ask.

Could really use some advice with this problem. Would load balancing help? I'm not convinced that my network is the issue (really not sure). Lots of streams, but the total speed is pretty low. Perhaps too many simultaneous writes to cache?

Not that I can particularly help, but does the time of all this happening seem to correspond with these numerous entries:

 

Aug 31 09:18:07 Brunnhilde kernel: TCP: request_sock_TCP: Possible SYN flooding......

 

Also intermittently you're getting share cache full errors which if you've got your containers set to use /mnt/user/appdata on a cache only share will give you nothing but headaches

I guess the times could correspond. Seems to happen at random and I can't say I really took note of the time.

 

Dockers are using /mnt/cache/appdata for configuration and /mnt/user/<nameofshare> for data. The cache full errors have been persistent on my server for months. Started well before any of the torrent dockers (or most of the others) were installed. The cache is never anywhere close to full when the errors occur. I've posted regarding them in the past but was never able to resolve the problem. Didn't seem to have any ill effects at the time.
