Dear all syslog-ng expert,

I have a pattern to combine multiple lines of postfix into a single entry. However, it does not work correctly. As I run syslog-ng -Fvde, I found out the reason is its context always expire after "from" log and "message-id" log which I don't know why. For example:
[2015-08-10T10:13:58.421999] Expiring patterndb correllation context; last_rule='bbbbbbbb-3916-2444-5238-7495cb64bf76', utc='1437843601'

I send you my debug output, patterndb and my log sample.
Please help me.
Thank you so much for your help.

PS: Sorry for my bad English.
