Hi all
I investigated more related to the seg fault which was noted in my email
below which means:
ctl_cyrusdb[1451]: segfault at 7261763b ip b73d8c41 sp bfbe2df8 error 4
in libc-2.12.so[b7368000+190000]
ctl_cyrusdb[2346]: segfault at 7261763b ip 00b21c41 sp bfc90508 error 4
in libc-2.12.so[ab1000+190000]
ctl_cyrusdb[3139]: segfault at 7261763b ip b74e8c41 sp bfc92df8 error 4
in libc-2.12.so[b7478000+190000]
ctl_cyrusdb[3449]: segfault at 7261763b ip b7505c41 sp bfa0c498 error 4
in libc-2.12.so[b7495000+190000]
ctl_cyrusdb[3539]: segfault at 7261763b ip b75d0c41 sp bfe71d38 error 4
in libc-2.12.so[b7560000+190000]
I can 100% confirm that this Messages are related to the entry in
cyrus.conf:
EVENTS {
# this is required
checkpoint cmd="ctl_cyrusdb -c" period=30
Always this happens in the Background in the log is shown:
Jul 23 17:09:34 kolab imap/master[13550]: process type:EVENT
name:checkpoint path:/usr/lib/cyrus-imapd/ctl_cyrusdb age:0.107s
pid:13857 signaled to death by signal 11 (Segmentation fault)
an the shown message above is shown under dmesg. From this Point of view
this happens on regular base (each 30 minutes). This issue seems to be
not new which means:
http://lists.kolab.org/pipermail/users/2014-September/017930.html
https://lists.kolabsys.com/pipermail/bugzilla/2014-October/017290.html
For a test I deleted the existing checkpoints db.backup* and startet
again. Within the start no issue no seg fault but after 30 minutes it
beginns from scratch. The Server is running now over 1 month and several
Domains and User are using the Server without of any issue. I tested
contact, calender, notes including Connections over IMAPS, SMTPS,
ActiveSync and so on...no Errors no issues. Full Debug mode was running
now over 1 month without any issues.
It seems to me a stability Problem? Anybody any Information regarding
such a issue? by the way I also cleaned up all db's excl. mailboxes.db
as annotations.db and imported a clean mboxlist but no Progress etc.
Kind regards
Andrea

Hi all there
I Setup in the last view days/week a Kolab Server based on CentOS 6.6
32bit and I have no issues with Kolab 3.4 which means I do not recognize
any None functionality even I enable full debug mode on the Services
like ActiveSync, roundcube, cyrus-imap, postfix etc. The Servers homes
about 7 Domains (seperated with multihome config). From this Point of
view I have to really say:
"hey guys from the developement - WELL DONE - I'm also impressed about
roundcube"
For your Information the Installation is running on:
Architecture: i686
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 4
On-line CPU(s) list: 0-3
Thread(s) per core: 2
Core(s) per socket: 2
Socket(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 28
Stepping: 10
CPU MHz: 1800.092
BogoMIPS: 3600.18
L1d cache: 24K
L1i cache: 32K
L2 cache: 512K
Of course it is not a Server or Installation which is installed out of
the box (not from installing Point of view) which means you have to
invetigate to understand the Server topology and what is for what
responsible etc. I had also contact with a friend which his Company is
doing security for Kolab Server. From this Point of view I created also
my own DH Parameter as restrictions on the protocols. From this Point
view I'm actually in testing Phase but it seems all is working fine :-)
To mentione again really WELL DONE guys from devel.
As it "must" be at the end :-) I have one/two message which is shown in
/var/log/message and in "dmesg" but to not have a misunderstanding
"There is no Impact in functionality of the Kolab Server" all is running
fine:
/var/log/message (showing up from time to time; since Setting preforc=1
for ptloader I do not have this Messages regularly)
Jul 15 12:34:50 kolab imap/ptloader[1463]: No entries found
Jul 15 12:34:50 kolab imap/imaps[1741]: ptload(): bad response from
ptloader server: identifier not found
Jul 15 12:34:50 kolab imap/imaps[1741]: ptload failed: but canonified
cyrus-admin -> cyrus-admin
dmesg (it seems that this message are appearing on regular base)

The first message regarding "ptload" as I feel after investigation in
several Forums etc. is making some other "Installations" also thinking
about but should not have any Impact on whatever?
The second one makes me thinking more....there is some message about
such Messages like:
https://issues.kolab.org/show_bug.cgi?id=3963
I do not 100% know if this is already pushed to cyrus-imap I do not
think so right? I have installed from Kolab Repo:
# cyradm --user cyrus-admin localhost
verify error:num=20:unable to get local issuer certificate
verify error:num=27:certificate not trusted
verify error:num=21:unable to verify the first certificate

If I'm right it should be the latest available Version! At least I would
like to mentione again:
I do not have any Impact all is working fine no Problem.
Does anybody have any Information about such Messages?
Any answer appriciated :-)
Have a nice day
Kind regards
Andrea
