Hi Patrick
After installing apache on ubuntu I type the following to use the
prefork version
sudo a2dismod mpm_event
sudo a2enmod mpm_prefork

Tim

Hi Patrick,
Your apache mp3 is probably set to something other than prefork. The
WOAdaptor does not support threaded mpm.

Hello everyone
Have a Ubuntu 20.04.3 LTS (GNU/Linux 5.4.0-90-generic x86_64) cloud
server with a number of WO applications deployed. WOAdapter was
compiled on the server. Apache (Server version: Apache/2.4.41
(Ubuntu)) is regularly crashing and for no reason. The application
remains unaffected but an error does pop up on the page from time to
time and occasionally going to next page hangs. Are considering
running the applications without the WOAdapter and wonder if anyone
has seen this and if there is a way to get around this error maybe
without resorting to the mod_proxy?

The "possible coredump" is a tease and is non-existent.
