FM server log files get big
I've been running FileMaker Server 12 advanced and the log files keep growing. Do you have advice on how to archive them and trim to keep just the recent log records? The wpc_access_log.txt file is at 820MB with 2 years worth of logs. I'd like to archive the records for 2013 and 2014 and only keep records for 2015 in the file. I wrote some scripts to do that but I had trouble overwriting the log file with just 2015's records. Apparently FileMaker Server has the file opened and won't let me overwrite. I'm running as administrator so I don't think permissions are the problem.
Any related advice would be appreciated.
