Segmentation Fault with dbmail 3.2.1 (FreeBSD)

 
Hello everybody.

We recently upgraded from 3.1.17 to 3.2.1 on two different machines and we’re now facing continuous segmentation faults both in dbmail-imapd and dbmail-lmtpd (on both machines).

We don’t have dbmail-pop3d active but I suppose that would be crashing too :-)  

The machine is a FreeBSD 10.1, I suspect there’s something strange going on with libzdb. Last line in dbmail.err is always the same when dbmail crashes:

There’s no dbmail-imapd.core or anything. 

The chain is the usual one: stunnel -> dbmail -> mysql 5.6

The machine is pretty busy but not super busy, after all it’s 29 dic.

What can I look for?

Thank you.
