AFP disconnect

Hi everyone,

 

I've been having a lot of trouble lately with the stability of my server. Lately, while I've been watching TV streamed from the server, the show will disconnect part way through. If I look at the unraid log, I see something like this:

 

Sep 11 17:30:49 fridge afpd[24063]: dsi_stream_write: Broken pipe
Sep 11 17:30:49 fridge afpd[24063]: afp_alarm: connection problem, entering disconnected state
Sep 11 17:30:49 fridge afpd[24063]: dsi_cmdreply(-1): Broken pipe
Sep 11 17:30:49 fridge afpd[24209]: dsi_stream_read: len:0, unexpected EOF

 

Looking in my console logs on my Macs, I'm seeing a lot of disconnects and reconnects to the shares. I'm also having trouble consistently mounting the Time machine share - sometimes it seems to work fine, other times the system will be unable to mount the time machine volume.

 

Has anyone seen this type of behavior before? Any suggestions on where to start my investigation?

    To make matters more interesting, I was attempting to run a fsck on the disks. It ran for about 15 minutes and then terminated abruptly. I logged into the web interface and noticed that the array had stopped itself. Here is the relevant log details:

    Very confused here.

    Out of curiosity, when you say you've been having trouble "lately," does that imply that there was a time when AFP was stable for you under moderate to heavy use?  I've seen one confirmed account of AFP working well for someone (understanding of course that folks who post on the forums tend to be the ones having problems), but I'm having ongoing issues myself, so I'm really just looking for data points on this to see if it's worth trying to save my investment in the unRAID license and hardware.  Thanks.
