Canto internal server error

[ValWood]

This has been happening to me quite bit recently but it usually goes away when I reload. I meant to mention it.

Right now, it seems permanent, see

ignore, it's back. might be worth checking it out though

I had a look in the logs and there is an error with no message. Let me know when you see the problem again so we can try to reproduce it.

It seems to happen when I hit the back to summary button after adding annotation (but not every time)

I can't track this down. There are some terse messages in the logs, but there's no details. Example:

Child process 9784 exited with status 0 - signal was 11

Signal 11 is a segmentation violation, which isn't suppose to happen in Perl. The most likely cause is a bug in the dodgy Lucene library we use for searching for term names and for auto-completion. The library has been unmaintained for 10 years so there's not much chance of fixing it.

The options for replacing that library are a bit painful. One possibility is use the search system from pombase.org:

• Use the main web site for auto-complete #1338

But we'd like to keep Canto independent of the rest of PomBase to make re-use easier for other groups.

We might be able to do something clever using the Solr/Lucene Docker container:
https://hub.docker.com/_/solr

There are other issues with the current system:

• Speed up ontology loading process #1911
