it think this bug might actually be a bug in the jk layer...
in ajp_process_callback, here is the block of code that handles sending the
next chunk of data from the webserver to tomcat:
--- snip ---
case JK_AJP13_GET_BODY_CHUNK:
{
unsigned len = (unsigned)jk_b_get_int(msg);
jk_log(l, JK_LOG_DEBUG, "received JK_AJP13_GET_BODY_CHUNK,
len=%d\n", len);
if(len > AJP13_MAX_SEND_BODY_SZ) {
len = AJP13_MAX_SEND_BODY_SZ;
}
if(len > ae->left_bytes_to_send) {
jk_log(l, JK_LOG_DEBUG, "len > ae->left_bytes_to_send
(%d > %d)\n",
len, ae->left_bytes_to_send);
len = ae->left_bytes_to_send;
}
if(len < 0) {
len = 0;
}
/* the right place to add file storage for upload */
if ((len = ajp_read_into_msg_buff(ae, r, msg, len, l)) >= 0)
{
r->content_read += len;
return JK_AJP13_HAS_RESPONSE;
}
jk_log(l, JK_LOG_ERROR, "Error ajp_process_callback -
ajp_read_into_msg_buff failed\n");
return JK_INTERNAL_ERROR;
}
break;
--- end snip ---
in this line:
if ((len = ajp_read_into_msg_buff(ae, r, msg, len, l)) >= 0){
shouldn't pmsg (the post message) be read into, not msg? i don't know the code
well enough to be sure....
anyway, i was running into a problem with an infinite loop in the ajp layer.
when i made this change, the problem went away.
