Serviio periodically slows down and stutters

Hi,

I am a huge fan of this media server and have been using it successfully for about 18 months. A problem has started occurring over the last few weeks. Every now and again while watching a high quality movie serviio starts to stutter and lag. This occurs in movies that I have previously watched with absolutely no problems. Pausing or rewinding seems to fix the problem for about twenty minutes and then it starts again.
I do not have transcoding enabled, and never did, and I have never had this problem before.
The media library is is on external harddrives connected to my PC which is connected by cables to a router and by cables to my LG Bluray player.
I cannot seem to attach the log file to this message for some reason so I have copied and pasted the log from a period when the problem appears to be occuring if that is any help.

Many many thanks for in advance for any help that can be offered.

Hi,
Using netstat and tasklist I was able to identify processes that were running on port 1900 and kill them/change port and now the "cannot bind" and "multicast socket" errors are not appearing on the log. The problem is still occuring, but less frequently. Here is the portion of the log that was recorded while another one of these stutter events occurred.

The problem does not seem isolated to the LG Player but also to the xbox.

Log looks fine. It could be network / IO related (considering there is no transcoding going on)
