Strange behaviour of Tomcat like a buffer overflow
Hi!
My application hehaves very strange in an unpredicable way. In both
apache and tomcat logfiles I see requests that seem to arrive in a
random order. The Tomcat logfile even shows HTML output of my servlets.
At times in the apache access log the request with HTTP GET parameters
is shown correct, but in tomcats access log the request is logged
altered with some garbage behind the "?".
My system config:
httpd-2.0.40.tar.gz
jakarta-tomcat-4.1.17.tar.gz
j2sdk-1_4_1_01-fcs-linux-i586.rpm
Here are a few lines from the Tomcat access log:
