I suspected that this may be related to that old issue since it disappeared
after the upgrade to 4.0.4.
I believe it is connected to the ajp13 protocol but I can not prove it.
The strangest thing is the length of the posted request - it is always power
of 1K.
BW you said that you fix the Processor but how you are detecting that the
connection to the httpd is closed without any changes in the C binary?
As I remember in the old "version" of this bug there was an infinite data
exchange between the httpd and Tomcat.
At that time trus was reporting something like:
0.0703 recv(26, 0xFFBEE4A0, 4, 0) = 4
0xFFBEE4A0: " A B\003"
0.0710 recv(26, 0x0025D888, 3, 0) = 3
0x0025D888: "061FFA"
0.0715 send(26, 0x0025F890, 4, 0) = 4
0x0025F890: "12 4\0\0"
0.0720 recv(26, 0xFFBEE4A0, 4, 0) = 4
0xFFBEE4A0: " A B\003"
0.0723 recv(26, 0x0025D888, 3, 0) = 3
0x0025D888: "061FFA"
0.0727 send(26, 0x0025F890, 4, 0) = 4
Was this completely because tomcat connector only?
