log4j不打印长日志消息

Question

在浏览日志文件时，我发现长日志消息部分打印在日志文件中。

我们正在使用以下ConversionPattern：

 <!-- The Modal -->
<div id="myModal" class="modal" style="z-index:1001">
  <span class="close">×</span>
 <%-- <img class="modal-content" id="img01" src="images/MeetingQA.PNG">--%>
    <img class="modal-content" id="img02" src="images/Meeting1.PNG" />
    <script>
        // Get the modal
        var modal = document.getElementById('myModal');

        // Get the image and insert it inside the modal - use its "alt" text as a caption
        var img = document.getElementById('myImg');
        //var modalImg = document.getElementById("img01");
        var modalImg1 = document.getElementById("img02");
        var captionText = document.getElementById("caption");
        img.onclick = function () {
            modal.style.display = "block";
            $(".box").hide();
            $(".categories").hide();
            $(".content").hide();
            //modalImg.src = "HelpDocs/MeetingQA.PNG";
            modalImg1.src = "HelpDocs/AR/Reports/Collection%20Completed%20Work/Collectioncompleted_Agent.PNG";
        }
        // Get the <span> element that closes the modal
        var span = document.getElementsByClassName("close")[0];

        // When the user clicks on <span> (x), close the modal
        span.onclick = function () {
            modal.style.display = "none";
        }
    </script>

  <style>
#myImg {
    border-radius: 5px;
    cursor: pointer;
    transition: 0.3s;
}

#myImg:hover {opacity: 0.7;}

/* The Modal (background) */
.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.9); /* Black w/ opacity */
}

/* Modal Content (image) */
.modal-content {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
}

/* Caption of Modal Image */
#caption {
    margin: auto;
    display: block;
    width: 80%;
    max-width: 700px;
    text-align: center;
    color: #ccc;
    padding: 10px 0;
    height: 150px;
}


/* Add Animation */
.modal-content, #caption {    
      -webkit-animation-name: zoom;
    -webkit-animation-duration: 0.6s;
    animation-name: zoom;
    animation-duration: 0.6s;
}

@-webkit-keyframes zoom {
    from {-webkit-transform:scale(0)} 
    to {-webkit-transform:scale(1)}
}

@keyframes zoom {
    from {transform:scale(0)} 
    to {transform:scale(1)}
}

/* The Close Button */
.close {
    position: absolute;
    top: 15px;
    right: 35px;
    color: #f1f1f1;
    font-size: 40px;
    font-weight: bold;
    transition: 0.3s;
}

.close:hover,
.close:focus {
    color: #bbb;
    text-decoration: none;
    cursor: pointer;
}

/* 100% Image Width on Smaller Screens */
@media only screen and (max-width: 700px){
    .modal-content {
        width: 100%;
    }
}
</style> 

log4j版本：1.2.17

我在生产日志文件中发现了这个问题，在本地计算机上它正常工作（打印整个日志消息）。

我们要打印整个日志消息。 它是否特定于平台？

你能帮我解决这个问题吗？
