h->conn = backend_connect(NULL, server, &mupdate_protocol,
"", cbs, &status);
Sorry, the crash is actually a few lines lower; it's dying in a call to
syslog. For some reason my core file is not lining up properly, and that
confused me:
if (!h->conn) {

I'll dig some more.

Looking further, I found core files on the mupdate master, from mupdate,
and suspect these are correlated with the downstream crashes.
In this case the crash is here:
#0 0x0036ed647e2c in vfprintf () from /lib64/libc.so.6
#1 0x0036ed6e4f10 in __vsyslog_chk () from /lib64/libc.so.6

We have a bunch of servers in a murder, and I recently took a look in
/var/lib/imap/cores and found core files for lmtpd/lmtpproxyd all over

front end imap proxy servers, the incoming e-mail servers, and the
mailbox servers --
