Too many Pixels files open.
1136 files open in total this time:

Logs and 'full lsof' attached below.
NB: file handle limit still quite low. Is it enough to fix this?

Mage was restarted yesterday morning. By yesterday afternoon:

Closed all uses of rawPixelsStore in webemdb views.py with a try / finally block http://github.com/will-moore/openmicroscopy/commit/62eb0596cc6224ac2c270f5a230706357b4c187d
Copied these changes over to mage, stopped server, created a clean Blitz.log and restarted
$ mv var/log/Blitz-0.log var/log/Blitz-0.log.3
Now it seems that doing projections, EMAN2 filtering or download dataset as stack do not accumulate file handles above a small number:
