Yes, they are uploading even full iso images with 4,7 GB as email
attachments. :-/
Which means, that SOGo will use up to 8 GB for MIME/base64 encoding it
in RAM!
We had several of those already.
When on a slow line, those uploads will break before finished and leave
those OGo* files behind.

Because of that we asked Inverse for upload limits.
Check WOMaxUploadSize and SOGoMaximumMessageSizeLimit.



Kind regards,

Thanks Christian, I'll check my cron settings.

For curiosity, why might a file get 1GB big? Are our students trying to
upload so big files? I hope not :)

Those files will be created, when someone uploads files to SOGo.
Which means when someone attaches a file to her email or imports address
books or calendars those files will be created.
Normally those will be removed after usage.
But sometimes they will be left behind.
Therefore we at the University of Konstanz have added the following to
/etc/cron.daily/sogo-tmpwatch

# Remove files in /tmp which are older than 7 days and starting with "OGo".
# Those are uploaded attachments not already send.
find /tmp -maxdepth 1 -type f -atime +7 -name 'OGo*' -delete


Be aware, that installing a new sogo version, will overwrite that file.
Because of that you have to add that again after updates, or you could
add it to /etc/cron.d/sogo

[SOGo] OGo*tmp files in /tmp - leftovers?

[goetz.reini...@filmakademie.de]

Hi,

I see a lot of up to 1GB big files in /tmp like OGo49B058BD278A0B.tmp

As they consumed all disk space we had some problems, so i was searching
for an answer what are the files for and can they removed at some point?

Thanks for feedback and regards . Götz
