TS5400R shares and web interface become unavailable until rebooted

[gman42]

I'm currently having an issue with a TS5400R (firmware version 2.40-1.28), which is being used by several servers as an overnight repository for backup data.  Every several days, during the period when data is being copied, the unit becomes unresponsive (usually able to ping it, but not access the SMB share or the web interface) until it's physically powered off/on.

We have all services other than SMB disabled on the box.  We placed a previous support call and had the unit replaced in case it was a physical problem, but the symptom is exactly the same.  The logs don't seem to show anything telling, other than the SMB log showing the expected series of messages like the following:

Dec 16 02:01:06 ASPNAS file_smb[32140]: [User:nobody(10.10.99.107)] File Open(Read) /mnt/array1/asp_data/.

...before stopping abruptly at the time it hangs.

There was a issue with the 5000 series that causes the unit to freeze when 100GB/s of data is being xfer. To me it was like 50GB/s of data. Updating to 2.43 should fix the issue but i had to factory reset mine to make the update work properly. The download is below and the update log. i have also copy/paste the updates from 2.40 to 2.43 below.

Thanks joma.  Silly me to trust the unit when it tells me it's already on the newest firmware.   ::)

No problem. Some times the firewall in your network is blocking the update request or there is a issue with the firmware getting the correct information. They just fix this for the linkstations that use kirkwood firmware. I would just ask buffalo support if there is a new firmware when you are having issue and if not i would back up your settings and do a factory reset. somethings the firmware gets all buggy.
