After few minute of work my Berkeley DB freeze. "greyfix --dump-triplets" shows no output.
All postfix process wait to access DB without chance:
nobody 12075 1 0 Jan08 ? 00:00:00 /usr/local/sbin/greyfix -/ 32 --greylist-delay 300 -r 451%sWait%s%d%sseconds%sand%stry%sagain%p.
nobody 12091 1 0 Jan08 ? 00:00:00 /usr/local/sbin/greyfix -/ 32
[...]
My configuration is:
postfix 2.3.4
greyfix 0.3.7
db4-4.1.25-8.1
Red Hat Enterprise Linux ES release 3 (Taroon Update 7)
DB freezed is like this:
[root]# ll /usr/local/var/lib/greyfix/
total 7616
-rw------- 1 nobody nobody 16384 Jan 8 22:12 __db.001
-rw------- 1 nobody nobody 278528 Jan 8 22:12 __db.002
-rw------- 1 nobody nobody 458752 Jan 8 22:12 __db.003
-rw------- 1 nobody nobody 7401472 Jan 8 22:12 triplets.db
Only if I delete all "db.00*" files it return to work for few minute.
