1: fatal signal 11 with AOLserver/4.5.1
Posted by Mattia Righetti on 11/01/16 12:32 PM

Hi everyone,
On a fresh installation of OpenACS on Ubuntu 14.04, this is what I find in the error.log file.

Does anybody has suggestion or ever found this scenario? How did you resolved the issue?

This is actually not a problem with OpenACS, but with AOLserver (I've adjusted the subject line); aolserver crashes before loading OpenACS. It looks like a broken module.

Dear Mattia,

although Aolserver is still officially supported, keep in mind that its latest release dates back to 2010, and all new development happens on Naviserver. Also, debian/ubuntu version of OpenACS is still 5.8.1.

Because of this, the project's official and suggested installation method is now by installer scripts here http://www.openacs.org/xowiki/naviserver-openacs

They will give you the latest Naviserver and the latest released OpenACS 5.9.0, requiring very little fiddling.

Hope this helps

Ciao
Antonio
