I discovered the contractors who built our Sympa environment for some reason set the TTL refresh rate to 24 hours (86400 sec). This was unexpected and undesirable. I changed sympa.conf’s  default_ttl to 1800 (30 minutes). I restarted services sympa and wwsympa Aug 17 22:14:44. After restart I checked several lists’ Data sources setup pages and confirmed their “Inclusions timeout (ttl)(default)” setting now said 1800. I expected this meant all lists would now refresh inclusions every 30 minutes.
 
However - it took two cycles of each list’s normal 24-hour refresh cycle before the 30 minute cycle started happening. For example, List A:
        - was refreshing at 12:18 daily
        - After the Aug 17 change/restart, it next refreshed Aug 18 12:18:07
        - It next refreshed Aug 19 12:18:27
        - Only then did it start refreshing every 30 minutes: 12:48, 13:18, etc.
 
Am I missing something about making sympa.conf changes take effect? This is 6.2.70 - the only thing I could find in documentation was that apparently the sympa.conf config is now “ttl” not “default_ttl”
 
Thanks
