After we upgraded to latest version of subversion, every time when svn command issued for repo with svn+ssh, it will end with error “Killed by signal 15”. It appears that it’s a subversion’s bugs.
To “hide” the error message “Killed by signal 15”, follow the steps below;
1. Edit ~/.subversion/config file
2. Under the “[tunnels]” section, usually it’s a masking for your ssh command, add the line below;
ssh = ssh -q
or look for the line below and uncomment it
ssh = $SVN_SSH ssh -q
3. Save the file. Now “Killed by signal 15” error should be killed by you 😉
