Hi,<br>
sorry, but the last time i forgot to egrep 'segfault|signaled'.<br>
The segfault patch doesn't exaplain the problem.<br>
I now created a new backtrace with more details:<br>
Core was generated by `ptloader -d9'.<br>

So, the problem is ldap related.<br>
I will downgrade to version git-12-2014 which worked for me so
far.<br>

Hi,<br>
just want to report back the reason of the segfaults.<br>
It seems, that an empty dc value is the cause of the problem,
then subsequent ldap calls causes segaults until the max
respawn limit has been reached:<br>

With version 2.5.0.0 (dev tree but stable cyrus release) the segfaults
came back.
I have to compile cyrus with debugging symbols enabled to dig deeper.
The actual bt:

<pre wrap="">Hi,
I upgraded a clone of my productive mailserver - but the ptloader errors

couple of testaccounts everything looks ok - but not in the productive

I hadn't had the time to get further in this problem - and I'm afraid
I'll lack of knowledge about cyrus ...
But did you find out more about the reasons of segfault? It seems to be
related to certain conditions of the setup. Otherwise a lot more people
should be affected.

<pre wrap="">Hi,
so far I didn't find time to look into this further. Also I'm not an
expert in cyrus and ldap as well... I might have a chance to look into
this again next week, but I doubt I'll find a solution by myself.
Anyway, thanks a lot for you input. It's good to know the bug still
exists with current cyrus.
Cheers,
Conny
