I'm running Ignition 8.1 on a linux server and I've noticed that one of my log files is huge compared to the other and doesn't seem to be closing out. I checked my ignition.conf file and the wrapper logging settings are the defaults:

wrapper.logfile.maxsize=10m  
wrapper.logfile.maxfiles=5

I've checked my Ignition/logs/ directory and I actually have 6 log files in there: wrapper.log, which is over 4GB, and wrapper.log.1 to wrapper.log.5, which are roughly 10MB. What has happened that caused the file to grow out of control and how can I fix it?

What version of 8.1.x is it? The default [implicit] [roll mode](https://wrapper.tanukisoftware.com/doc/english/prop-logfile-rollmode.html) is `wrapper.logfile.rollmode=SIZE`, so it should roll upon that size exceeding 10MB. I've never observed it malfunctioning--I imagine that might be _something_ in that log file related to the Java Service Wrapper if it tried to roll and failed for some reason. Are the file permissions on the existing `wrapper.log.*` files correct (i.e. the user that Ignition is running as still has r/w access to them)?

Also, was Ignition restarted after changing the configuration?

Sorry for not replying sooner. The version is 8.1.10. I checked my config file and didn't find a `wrapper.logfile.rollmode==SIZE` property in the config file. It looks like the log file permissions are correct.

The issue has resolved itself after a gateway restart.
