- Create a branch for Solr 4.10.4 changes so I can test on DSpace Test (linode19)
|
||||
- Deployed Solr 4.10.4 on DSpace Test and will leave it there for a few weeks, as well as on my local environment

- It's been two days since we had the blank page issue on CGSpace, and looking in the Cocoon logs I see very low numbers of the errors that we were seeing the last time the issue occurred:

- To investigate the Solr lock issue I added a `find` command to the Tomcat 7 service with `ExecStartPre` and `ExecStopPost` and noticed that the lock files are always there...
|
||||
- Perhaps the lock files are less of an issue than I thought?
|
||||
- I will share my thoughts with the dspace-tech community
|
||||
- In other news, I notice that that systemd always thinks that Tomcat has failed when it stops because the JVM exits with code 143, which is apparently normal
|
||||
- We can add `SuccessExitStatus=143` to the systemd service so that it knows this is a successful exit
