*** glibc detected *** lmtpd: double free or corruption (out): 0x00002aaaacdeaa10 *** : 2 Time(s) problem

[Alain Spineux]

What I understand is this :

When postfix try to deliver an email, it open a LMTP connection with cyrus
and cyrus, instead of speaking correct LMTP reply with garbage.
BUT 2aaaac388000-2aaaac479000 r-xp 00000000 fd:00 12452057 /lib64/libdb-4.3.so
is not realy garbage this look like to be the memory areas of a process.
Try a
# cat  /proc/XXXX/smaps | grep "^[0-9]
where XXXX is any valid process PID, you will see :-)

How do you stop/start cyrus ?
Do you use the usual sysV startup scripts ?
If so could you shuthdown cyrus, login on the console of the computer,
(not a ssh or a telnet) and start cyrus using

# /usr/lib/cyrus-imapd/cyrus-master -d

and see if the problem append again
