Unexpected Exception occurred at indico: Impossible to compile

Hi!
I found this repetitive message in my email from indico:

Subject: Unexpected Exception occurred at indico.fis.cinvestav.mx: Impossible

‘/opt/indico/tmp/indico-texgen-M4VH5B/output.log’ for details

The output.log is:

What can be happening?
If is not an error, how can I disable this messages ?

Thanks!

That seems very strange. For some reason it could not create the output PDF file in /opt/indico/tmp/indico-texgen-mzWPfe/, but unfortunately it did not include any details why.

Indico sends these emails whenever an unexpected error happens - if you got many of them probably it was e.g. googlebot accessing one of the PDF pages in Indico, and triggering the error whenever it was accessed.

The only way to disable this would be to disable all error log email by editing /opt/indico/etc/logging.yaml and removing the email handler from the indico logger.

thanks, I think not deactivate the messages, but try to see what happens, some other idea ?. regards

One possible cause: No space left on the partition(but then normally the logfile would get truncated as well. Or running out of inodes?
To check you can use:
cd /opt/indico/tmp/
df .
df --portability --inodes .
