I just tried to upgrade our instance from version 4.2.11 to 4.4.3
After some issues with a missing user www the installation process seemed to complete successfully.
But the server fails to start. The only thing i can see in the appache2/error.log is:
[Thu Feb 14 17:49:31.647432 2019] [:warn] [pid 2063:tid 140343025874816] FastCGI: server “/opt/rt4/sbin/rt-server.fcgi” has failed to remain running for 30 seconds given 3 attempts, its restart interval has been backed off to 600 seconds
The request tracker log shows no errors after upgrading.
This is usually due to linux file rights, you can start by making sure that the apache user ‘www-data’ has access to the necessary files. You can also run make fixperms from the RT source directory to have the permissions set by RT.
When you did the upgrade did you use the same Perl as originally? I have run into the problem before where Apache didn’t have execution right for the Perl pointed at by RT files #!/some/path/to/perl -w.
When you do ls -l on your /opt/rt4/sbin/ directory what rights do the files have?
