http://issues.apache.org/bugzilla/show_bug.cgi?id=28713 Line too long - DoS Attack Summary: Line too long - DoS Attack Product: Tomcat 4 Version: 4.0.3 Final Platform: Other OS/Version: Other Status: NEW Severity: Critical Priority: Other Component: Catalina AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] Somebody is attacking my Tomcat Server sending a big HTTP header. When the server gets this request it throws an IOException and the HTTPProcessor hangs. The exception is: HttpProcessor[80][1] process.parse java.io.IOException: Line too long at org.apache.catalina.connector.http.SocketInputStream.readRequestLine (SocketInputStream.java:271) at org.apache.catalina.connector.http.HttpProcessor.parseRequest (HttpProcessor.java:695) at org.apache.catalina.connector.http.HttpProcessor.process (HttpProcessor.java:959) at org.apache.catalina.connector.http.HttpProcessor.run (HttpProcessor.java:1107) at java.lang.Thread.run(Unknown Source) After all HTTPProcessors are hung every connection to the server fails. This issue is related to Bug 3511. The HTTP port is able to respond but cannot respond since there aren't processors available to handle the request. The catalina log keeps showing: "HttpConnector[80] No processor available, rejecting this connection" Are there any workarounds for this issue? I don't understand why the processor hangs since this should be a handled exception...
