[ome-devel] TempFileManager:rmtree error

[Andrii Iudin]

Dear OMERO developers,

I am running OMERO 5.2 on Linux and am getting the following error 
message when doing bin/omero web start:

ERROR:omero.util.TempFileManager:rmtree error: 
rmdir('/homes/andrii/omero/tmp/omero_andrii/21187') => [Errno 39] 
Directory not empty: '/homes/andrii/omero/tmp/omero_andrii/21187'

The content of 21187 directory is a .nfs file that seems to be created 
when the original file is removed but is still being accessed by a 
process. The .nfs file is removed when bin/omero web stop is performed, 
but the directory remains.

This does not affect the work of OMERO, however it creates empty 
directories in /homes/andrii/omero/tmp/omero_andrii/ which can slow down 
the system unless handled. A similar issue is mentioned here:
http://lists.openmicroscopy.org.uk/pipermail/ome-devel/2014-September/002990.html

Permissions and ownership on such directories are the same as the rest, 
however the Apache server is running under a different user. Can this be 
the cause of this problem as it is mentioned here:
https://www.openmicroscopy.org/community/viewtopic.php?f=5&t=386#p1064
?

If so, is there any other solution except running the Apache server and 
OMERO as the same user or setting a script to regularly remove empty 
folders in tmp?

Thank you and best regards,
Andrii
