Hi all, I have one webserver dedicated for a client communication running apache 1.3.22-6 on linux red hat 7.3 and almost unused. Today the machine had no memory or swap left (1 gig memory,512 meg swap). Analyzing the error logs I found this: Lots of in /var/log/messages: Oct 12 20:31:24 web01 kernel: Out of Memory: Killed process 1023 (httpd). Oct 12 20:31:52 web01 kernel: Out of Memory: Killed process 1016 (httpd). Oct 12 20:32:22 web01 kernel: Out of Memory: Killed process 1020 (httpd). Oct 12 20:34:04 web01 kernel: Out of Memory: Killed process 1026 (httpd). Oct 12 20:34:53 web01 kernel: Out of Memory: Killed process 1025 (httpd). Oct 12 20:35:55 web01 kernel: Out of Memory: Killed process 1031 (httpd). Lots of this in error log: [Sat Oct 12 20:41:44 2002] [error] child process 1227 still did not exit, sending a SIGKILL [Sat Oct 12 20:41:44 2002] [error] child process 1228 still did not exit, sending a SIGKILL [Sat Oct 12 20:41:46 2002] [error] could not make child process 1072 exit, attempting to continue anyway [Sat Oct 12 20:41:46 2002] [error] could not make child process 1080 exit, attempting to continue anyway Few minutes before in error log: [Sat Oct 12 20:16:19 2002] [error] [client 217.223.216.186] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): / [Sat Oct 12 20:21:09 2002] [error] [client 207.99.78.36] request failed: erroneous characters after protocol string: CONNECT maila.microsoft.com:25 / HTTP/1.0 This connect maila looks like someone trying to find some kind of proxy. What about the empty hostname? I cant figure out why that happened.
