Hello,
I'm having this error:
Warning: If you are seeing this message, your log files may not have
been
checked!

Details:
Could not run logtail or save output

Check temporary directory: /tmp/logcheck.EIX3jp

permisions on /var/log are all 640, permissions on /var/lock/ are 777
what can be the problem?
