WebApp is not showing mail content - apache2 seg fault

Hello,

I have a bigger challenge, in webapp I cannot see the message body anymore.
E-Mails are also not delivered via Z-Push anymore.

I did an update to
WebApp: 3.4.0.668-470.1
Kopano Core: 8.4.0-596
Z-Push: 2.3.6

Apache version is 2.4.25

In apache I am getting [core:notice] [pid 16060] AH00052: child pid 16124 exit signal Segmentation fault (11)

for me, it looks like php-mapi is not working anymore, can you please help.

I also did a full re-install of my ubuntu 16.04 AMD64 server.
Everything works fine and without issue until I install webapp, then seg fault is comming…

Thanks

Ihon

I would say this is data related. Could you let apache write the core dump to disk and send it to support (at) kopano.com?

You can create a core dump as described here: https://serverfault.com/a/470410
Please inform the exact version & build numbers you are using.

Cheers,
Sebastian

I’ll send the coredump later today.
I am quite sure, it is not data related as it affects z-push as well.

Even when I install Ubuntu, kopano core then z-push I get the seg fault.

Thanks,

Ihon

Core Dump sent, details and build numbers are attached in the mail.

Thanks

Hello,

I got the same error with version 3.4.0.670-471.1
AH00051: child pid 7516 exit signal Segmentation fault (11), possible coredump in /etc/apache2

Please fix it as soon as possible.

It is not possible to open mails.
Active-Sync (z-push) is also not working.

Please fix it as soon as possible.

Hi @schmidt,
rolling back to core-8.4.0~553 might be the faster fix:

Delete the latest row in table “versions” of your kopano-db before starting the downgraded kopano-server and you’re done.

mysql -hlocalhost -ukopanouser -Dkopano-dbname

DELETE from versions WHERE databaserevision=66 AND revision=596;
QUIT

++umgfoin.

Where to download?
I do not have the old version anymore and in the comunity edition only a newer one is available.
It would be really cool if kopano could provide the old one until this issue is fixed :-)

Regards,

Ihon

Short info, webapp-3.4.0.670_471-Ubuntu_16.04-all and core-8.4.0~636_135.1-Ubuntu_16.04-amd64 do not fix the issue

Thanks,

Ihon

Hello community,

Thank you for reporting the issue.

We were also able to reproduce it on our test systems and have created a fix in version 8.4.0-644.

Please upgrade your systems to this version (it’s just been published to the community) and let us know if the problem has been resolved.

Kind regards,

Joost

Hi Joost,

thank you!
It is working again :-)

Thank you all
