Problem with Samba shares

[alienjon]

I setup a Gentoo machine to act as a home server. I'm running Samba off the machine and have been transcoding videos for a Plex server. Recently, as in the last few days (possibly since an update, come to think of it, though I don't believe Samba was among the updated programs) I've found two issues occurring that I believe to be related. Firstly, there have been several instances where the mapped Samba share on my Windows 10 machine weren't able to reconnect. A simple 'disconnect drive' and 'connect drive' resolved the issue, but as it came up a few times I'm not sure what happened (I didn't have to touch the server at all for this). The second issue is that during transcoding (where I'm taking an original file on a network drive, transcoding via Handbrake in Windows 10, and saving to the new file on the share) the process will randomly stop. It seemed random, and I'm not entirely sure it isn't a problem with something else (though sometimes running the same action again on the same file will succeed, so I don't think it's the files) but I believe this is also connected to the Samba share because there was one instance where I was using my Windows 10 machine as the transcoding process failed and the mapped drive got messed up at the exact same time.

I suspect Samba, because a) they are Samba shares and b) I can still SSH and otherwise connect to other services on the server. I'm not getting any error messages in Handbrake (Which is exceedingly frustrating, because it will simply say that the transcoding failed without any detail - even the detailed debugging only gives more info on the transcoding process, not any errors).

Timeframe could be correct, except I'm running the latest stable. 4.5.6 is masked. I'm on 4.2.14:
