[users@httpd] Re: users Digest 30 Jan 2019 15:52:55 -0000 Issue 5789

Hi Luca,

Thank you for your information.
I tried to debug this situation as was described in article.
But unfortunatelly I was able to do only core dump from this fall. I'm 
sending you this dump file. Are you able to identify in which module is my 
problem?

Thanks
Jan

could you follow http://httpd.apache.org/dev/debugging.html#crashes
and report back the stacktrace of the segmentation fault? It would be
very useful to understand what module is triggering this. mod_cluster
is not part of the standard httpd distribution, so in case of issues
with it I'd suggest to follow up with them to get more info about how
to fix the issue.

Thanks!

Luca

Hi Jan,

I tried to check the tar.gz but I only see traces files (I suppose
from strace) and an error log, meanwhile what I meant in my last email
was a core dump file. I am afraid but with what you provided is a bit
difficult to understand what is the problem..
