Help! On a production system that's been rock-solid for 18 months, Tomcat is suddenly hanging on a daily basis!
Before the server hangs, we're logging runtime exceptions from SocketInputStream.readHeader: the log records ArrayIndexOutOfBounds exceptions every second for a few hours, then the server responds to every subsequent request with a 400 "Bad Header" response, ie. hangs. The same/similar problem was reported a year ago, see http://www.mail-archive.com/[EMAIL PROTECTED]/msg85861.html Can anyone shed light on what is happening? Or suggest a workaround/fix?
