Describe here your question/suggestion/issue (expected and actual results):
I kindly ask for help as I struggle with some errors after redmine stack failure.
Nearly 2 weeks ago redmine 4.1.0-0 as VM was working unstable (some people could not log in, some issues could not be seen), therefore the VM was restarted. After the reboot, everything seemed OK, but over time problems appeared:
- some users' sessions are disconnected with a message: error seesion expired.
- some users have started to receive reminders regarding closed issues. I checked some of these issues in mysql table and their status is set as closed.
- there is a problem with the delivery of email notification. In production log for some issues (I don't see a rule) there is a message: email delivery error: execution expired.
I would like to add that I used previous ver. 4.0.2 with mysql and db as utf8. Version 4.1.0 uses utf8mb4 by default and the previous db. has been imported to utf8mb4. When there were problems, the database was exported, mysql set as utf8 and a bit earlier export data imported as utf8, I hope correctly.
Mysqlcheck return OK for all tables..
Apache log does not contain errors except update checker, eg. [ E 2020-02-23 14:22:23.0630 1095/Ta age/Cor/SecurityUpdateChecker.h:507 ]: Security update check failed: Couldn't resolve host name while connecting to https://securitycheck.phusionpassenger.com/v1/check.json (check your DNS) (next check in 24 hours))
So, please give me advice how to debug / fix these issues.
