| Hi,
We are deploying on Ubuntu 14.04.2 LTS, so it looks like we have to use Apache 2.4 (Apache/2.4.7) We have built the correct adaptor, and it pretty much works as expected.
But, after a while, Apache appears to stall.
The apache error log states: — [Fri Mar 20 17:27:57.342752 2015] [:error] [pid 22139:tid 139805346232064] Invalid response!

(not sure the last 2 lines are anything to do with it).
To get it working again, I have to completely stop/start apache (a restart doesn’t appear to work).
"WOShmem_unlock()” might implicate the WebObjects adaptor.
Has anyone seen this behaviour before, or know how to fix it?
Thanks in advance,
Mark Gowdy
