Structure plug-in: derby.log and db directory disk usage

Hi there,

We're finding the the structure derby.log file grows quickly, consuming large amounts of disk (usually around 10GB in a few days).  Can the logging to this file be made less verbose?

The /db/ directory in the structure directory also grows quickly.  Can any maintenance be performed within Structure to control the size of this directory?

Normally derby.log should stay very small. Extensive logging is enabled explicitly or when JIRA is in “development” mode. You can check if Structure turns on verbose logging by searching atlassian-jira.log for the line "Structure turns Derby verbose logging on” - it would happen shortly after JIRA start or Structure enablement. (You can disable / enable Structure to see if that produces this message.) 

If it’s on, you can force it to be off with “-Dstructure.derby.verbose.log=false” system variable (added in / setenv.bat).

Another possibility is that Derby database became corrupt on your server, and derby.log contains errors. In that case, the users should also experience problems with Structure. If that seems to be the case, we'll need the ZIP of the derby.log file so we can take a look.

Kind regards,
