I must start by admitting that I might have jumped the gun on this one. I first started to experience the issue after upgrading from FileBot 4.7.9 to 4.8.2. Found this thread which error description matched my situation. Upgraded to the mentioned beta version 4.8.5 (r6064) and the situation persisted, hence I have not confirmed it to be the very same issue as presented by goofy183.
From looking in to it a bit more closely, especially the dmesg content, it does look to be related to the FileBot copying action and the cifsd daemon.
Presenting a share called "mediaserver".
Accessing the share "mediaserver" over cifs while hosting an instance of Transmission and FileBot.
Note: The run is resulting in the error state of the vm and me killing the process.

I hope that this information if of use to you, please advice if I can provide any additional information.
If you're an advanced user, then you can use VisualVM to create a heap / thread dump so we can see exactly where each application thread is stuck.
