[syslog-ng] Problems creating syslog-ng.persit- file

Fri Mar 7 17:48:16 CET 2014

Hello,

No it did not.  Here is the debug output when I try to use the JFFS2 directory to store the persist file:

I hope it helps.

It should have reported the issue more explicitly though.

Did it offer any diagnosis when it failed?

That explains it, I was not aware that syslog-ng created a temporary file with the '-' suffix first.

Thank you.

syslog-ng first creates a tempfile having the '-' suffix then uses mmap(). A quick googling showed that jffs2 doesn't support mmap()
