[380:34] is [pid:tid] of the process and thread.

"ajp_connect_to_endpoint::jk_ajp_common.c (985)" is the file and line
number on which the error occurred. So, if you look at jk_ajp_common.c
on line 985, you'll find that it's in the ajp_connect_to_endpoint function:

        if (rc == JK_FALSE)
            jk_log(l, JK_LOG_ERROR,    // Line 985
                   "(%s) cping/cpong after connecting to the backend
server failed (errno=%d)",
                   ae->worker->name, ae->last_errno);


All of this is in the code: you only have to look at two source files to
discover what I have posted.
