<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Thanks for that information. I do have a tendency to do a lot at one time. I'll watch for that and try again.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I found in the documentation:</p>

This implies there is a limit to the number of files and directories your process can monitor simultaneously. On Mac OS X 10.4 and all BSD variants, for example, an open file descriptor is required for each monitored file. Some system limits the number of open file descriptors to 256 by default. This means that <a href="http://harmattan-dev.nokia.com/docs/library/html/qt4/qfilesystemwatcher.html#addPath"><span style=" text-decoration: underline; color:#0057ae;">addPath</span></a>() and <a href="http://harmattan-dev.nokia.com/docs/library/html/qt4/qfilesystemwatcher.html#addPaths"><span style=" text-decoration: underline; color:#0057ae;">addPaths</span></a>() will fail if your process tries to add more than 256 files or directories to the file system monitor. Also note that your process may have other file descriptors open in addition to the ones for files being monitored, and these other open descriptors also count in the total. Mac OS X 10.5 and up use a different backend and do not suffer from this issue.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">So you may try to reduce the number of folders, or find other applications that keep files open.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:40px; margin-right:40px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">Hope this helps.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:80px; margin-right:80px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">I do a lot of work with Digikam. Resizing, sharpening, colour correction, renaming, etc. I have found in the past few weeks that I can open Digikam, do a bunch of work, and close Digikam just fine. However, if I restart Digikam without restarting Kubuntu I get a large number of error messages of the type:</p>

If I do a system restart then Digikam opens properly and works well. Does anyone have any suggestions?<br />-- </p>
