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

[Eugenio Trumpy]

Hi,

I still have problems on saving maps. I followed the suggestions of Francesco to try to use gdb on apache coredump, but apache seems not able to write this file in /tmb/apache-coredumps. I don't understand why, I also changed the owner of such dir.
On saving map I got always the same error:
[Thu Dec 10 10:10:57.505105 2015] [core:notice] [pid 26683] AH00051: child pid 20374 exit signal Segmentation fault (11), possible coredump in /tmp/apache-coredumps

but on geonode frontend the map seems to be saved (without thumb). Differently to what happened before (I mean before the update of the server from ubuntu 12.04 to 14.04 when I clicked on a listed map I got the error I mentioned here: https://lists.osgeo.org/pipermail/geonode-users/2015-October/001002.html) now if I click on a listed map I got no error and I see the description page, where I can choose 'view map', consequently the map is displayed but empty, without the layers I included. In the db the record on table 'maps_map' is inserted but  only 3 filed are filled-in(the id, supplement_information and last_modified).

The segmentation fault do not allow the transfer of the map info to the table db.
What is strange is that up the geonode upgrade the system worked fine.
Any further suggestions?

kind regards

Eugenio

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
