Re: Failed allocating AJP message buffer
Hello Rainer I already check for memory and for sure it is not a physical memory issu. We have 12Go and the memory usage is around 6Go at the moment of the crash.

The HTTPD.EXE recylcle itself, users are disconnect and then the service come back online. I did lot of search on those message but i cannot find any solution. Some help would really be appreciated! It seems you are out of memory. Either - there's some leak in your Apache, most probably in some non standard module - or your server is very tight on memory - or your application inside Tomcat is getting slow, so there are more and more requests getting stuck inside Apache waiting for a response from the web app and those requests consume to much memory. There are MPM settings for Apache on Windows that limit the number of threads (=connections =~ concurrent requests) Apache will allow. Monitor your server memory usage.
