We've been doing some reconfiguration to try to track down some issues and
with one of the changes, we are now getting a number of errors (but not all
the time) like this one:
[8624:1188] [info] jk_ajp_common.c (840): awaited reply cpong, received 3
instead
[8624:1188] [info] jk_ajp_common.c (1237):

[8624:1188] [info] jk_ajp_common.c (2085):
(810ED18641A24B1784CF0575992D73C7) sending request to tomcat failed,
recoverable operation attempt=1
In all instances of the error, it always says "received 3 instead".
3 ist a JK_AJP13_SEND_BODY_CHUNK packet. We are waiting for a 9
(AJP13_CPONG_REPLY). So this is a protocol error. Very strange. Not a
known problem.
What's special about "one of the changes"?
Can you easily reproduce, or will it happen only sporadically?
Any idea what could be causing this issue?
Thanks,
Darin
