[GeoNode-users] error on saving maps, again!

[Eugenio Trumpy]

Hi Francesco and all,

I followed your link, and I tried to debug apache. However I'm not able to get the core file. 
I think I did the correct procedure, I added the suggested packages, created the dir in /tmp,
added the line: CoreDumpDirectory /tmp/apache-coredumps in /etc/apache2/apache2.conf
retsarted the apache, without errors.
Then I tried to save map on geonode to get the seg-fault. On the error. log I got:

[Wed Dec 09 13:48:25.299288 2015] [core:notice] [pid 18000] AH00051: child pid 18004 exit signal Segmentation fault (11), possible coredump in /tmp/apache-coredumps

In the /tmp/apache-coredumps there is no files.
So I cannot go toward gdb debug.

I thought my problem was due to the dir owner, so I changed the grants to www-data for /tmp/apache-coredumps/ dir.

Am I missing something?

Can you help me?

E.

Eugenio,
a possible way to investigate more your problem is to attach httpd child process to gdb, cause it’s not reproducible. Follow instructions in this blog [1] and then look at the next crash.

Hi Francesco,

I'm trying  to use geonode 2.4.dev20151203130956.
I tried to save both an empty map and one containing a wms from an external geoserver. Same error.
I also tried to upload a new layer for using it on a new map, but that geonode version misses the category choose, so I got error also on upload a shp file.

Any idea on the reason of my problem?

Eugenio

Hi Eugenio,
what version are you running? Did your unsaved map contain remote any layer from remote service?

Dear Simone and all,

I'm very sad to announce you that I'm getting the same error I got 1 month ago.
I got an error on saving maps, and I retrieve the same error in apache error.log:

[Fri Dec 04 16:40:39.271057 2015] [core:notice] [pid 15782] AH00051: child pid 26334 exit signal Segmentation fault (11), possible coredump in /etc/apache2

same stuff on segmentation fault!

I can consider me very unlucky on this installation.
Actually It was 10 days up to yesterday that I did not use geonode, but I'm sure it was working fine.
Yesterday I had the problem raised on the geonode user mailing list, so today I decided to upgrade all geonode system.
The installation went fine, but I have the same problem on saving map.

I don't understand what happen. 
I solved this problem upgrading the server from 12.04 up to 14.04 version. This task was a bit time spending but all the applications
as well as geonode then worked fine. 
In the meanwhile no important activities I performed on the server, only a few OS update.

Can you help me again?

Eugenio
