So is this fixed now?
The last time I checked, it was still broken. Since Michael hinted 
that het was tempted to remove the SQL cache driver, I assumed it was 
scheduled for removal, so I never bother checking again. I'll check 
again during off-hours, since if it is still broken, it will break 
active sessions (bad idea during office hours).

Hi,
So is this fixed now?
so, if the solution is, not to use the SQL based cache storage, it is 
fixed BUT in my personal opinion it was NOT fixed, the problem is only 
solved?

Thank you,
Klaus.

Hi,
And which cache driver were you using before?
Bevore, I used --> SQL-based cache storage (NOT RECOMMENDED) <--

But, since I disabled the cache, my personal feeling is, it's faster
than before :-)

Thank you for that, so i will never use SQL based cache storage. For 
testing, I switched to File based caching.

Solved for me!

Thank you, for your fast help!
Klaus.

Hi,
next step to solve the problem: I enabled dynamic view AND chenged
the settings:
HORDE | Caching | Caching Setting |  $conf[cache][driver] to Don't
cache any data
AND the problem was gone.

Hi,

when I use MySQL-PDO driver and NOT the dynamic view, anything works 
fine, but I made only a view test - BUT I can read e-Mails and can 
use the calendar too!
It works with the MySQLi-Driver too!

Thank you
Klaus.

Hi,

after updateing from horde 5.0.4 to 5.1.0 some actions in horde causes 
following problem to my apache:

  --> child pid xxxxx exit signal Segmentation fault (11)

My System:
- CentOS 6.4 (with latest updates, fully patched)
- Apache/2.2.15 (Unix) PHP/5.3.3 mod_ssl/2.2.15 OpenSSL/1.0.0-fips
- Cyrus IMAPD Version 2.3.16 (no problem with outlook, evolution or K9Mail)

How the error occures:

1. After loggeid in in horde (Dynamic View) | click on Webmail | Click 
on any e-Mail in the list - "Fehler während der Kommunikation mit dem 
Server" pop up will shown!

In the apache log, following entry will displayd (Apache error code 500):

"POST /services/ajax.php/imp/viewPort HTTP/1.1" 500 835 
"https://buero.tachtler.net/imp/dynamic.php?page=mailbox" "Mozilla/5.0 
(Windows NT 6.0; rv:21.0) Gecko/20100101 Firefox/21.0" TLSv1 
DHE-RSA-AES256-SHA

And on apache error_log following entry will displayd:

child pid 5848 exit signal Segmentation fault (11)

It seems to me, that, maybe a looping function will be crasch the 
apache child process.

2. Same problem, when i used to open the calendar!

3. Some other things, like the address book could be used without any 
problems.

PLEASE, help me using my Horde again!

For ANY other Information, please contact me, I will to my best to 
sent you log files, config files or anything else...

Thank you!
Klaus.
