Thread:Project:Support desk/Mediawiki won't let me save an edited page

Hi all,

I have the Mediawiki running fine in a Ubuntu 12.10, but after 2 or 3 days, it shows an "error loading page" when I try to save or preview an edited page.

In the "error.log" file, the only line logged is:

"[Fri Mar 27 10:09:37 2015] [error] child died with signal 11"

Have someone have this problem before?

Thanks!
