Watcher60,
I tested the scenario that u mentioned, and indeed ltm.1 file was gone the next day.
If I add nocompress /var/run/config/logrotate.d/syslog-ng then ltm.1 file will be there.
So it looks like the compression touch the ltm.1.
THIS IS AN AUTO-GENERATED FILE -- DO NOT EDIT!!!
Use the bigpipe shell utility to make changes to the system configuration.
For more information, see bigpipe logrotate help.
