>Description:
System crashed after 21 days up within hours of having copied a large (200MB) file over NFS from a Linux system on a 100baseT switched network. The crash occured while another system was copying several small files to the same NFS share.
I can obtain debugging information from the system when it recurs (third time since 4.4-STABLE), but will require personal correspondence on how to set up the environment for that.
>How-To-Repeat:
Difficult to repeat - randomly occurs when the filesystem is actively being written to.
>Fix:
Not yet known.
