<p style='margin-top:0;margin-bottom:10px;'>I had a problem tracking down why every third rolled log file was missing (see <a href="https://www.mail-archive.com/logback-user@qos.ch/msg04293.html" class="external-link">https://www.mail-archive.com/logback-user@qos.ch/msg04293.html</a>). Turns out the underlying problem was we had write and execute permissions on our log folder, but not read. So, logs were being created, and 2/3 of our rolled log files were being created, with no info in the catalina.out (we're running under tomcat), or in the log files themselves.</p>
<p style='margin-top:0;margin-bottom:10px;'>The symptom was being caused by code in SizeAndTimeBasedArchiveRemover, which calls FileFilterUtil.filesInFoderMatchingStemRegex(), which returns null when there are no read permissions.</p>
<p style='margin-top:0;margin-bottom:10px;'>Suggestion: Add a check, perhaps in FileFilterUtil, which checks to see if the return is null (indicating an I/O Error according to the java.io.File docs), and if so, indicate that somehow - even if only when logback is running in debug mode. (Currently, when running debug mode, there's an NPE thrown from SizeAndTimeBasedArchiveRemover, since the code assumes a non-null response from filesInFolderMatchingStemRegex).</p>
<p style='margin-top:0;margin-bottom:10px;'>Thanks!</p>
