Apache crashes time-by-time and the system is not reachable by SSH
I running an apache web server on Fedora 15. Basically it runs fine but all couple of days my server is down and even not reachable any more by SSH. I get something like
ssh: connect to host 192.168.1.13 port 22: No route to host
In the error logs of the httpd I sometimes find something like:
[Fri Mar 02 07:38:09 2012] [error] (12)Cannot allocate memory: fork: Unable to fork new process
as last line, but not always. Anybody can explain that behavior, especially why the server is no longer reachable by SSH?
Thanks a lot!
