Hello,
I am using here Debian Jessie whith classic Raid1 mdadm, with two ssd devices
(Crucial_CT256MX100SSD1) and btrfs 3.14-2-amd64 #1 SMP Debian 3.14.13-2
(2014-07-24) x86_64 GNU/Linux.
The server under load. After some days or a week is see in messages (log files,
see below.).
The server is not freeze but works not correctly. There are no possibility to
reboot.
Is this a bug? May be somebody has an ider for mount options or kernel
upgrade?

Please include outputs of
btrfs fi sh /
btrfs fi df /
Also I do recommend against using SoftRAID on SSDs until SoftRAID actually
uses ATA TRIM to sync empty areas of both devices to one another. I am not
sure whether it does so in 3.14.
Otherwise lets see what BTRFS developers have to say about this backtrace.
Since it happens with 3.14 it does not seem to be related with the hangs after
switching BTRFS to workqueues which happen in 3.15 and 3.16. There are two
patches related to fixing this issue, but the fix may still be incomplete.
Thanks,
Martin

Okay, so in both data and metadata case there still appears to be free space
within the tree. That and that this happens with 3.14 and the different
backtrace seems to point at a different problem than the hang issues since
switching BTRFS to workqueues with 3.15 and 3.16.
Well, maybe a developer can help here.
