I'm sure the problem is the usual confusion between MB and MiB. Try to not use a very close value, in your case i would use 3000 mb as limit. For example, i would consider a bug if it reaches 3500 mb and the limit is on 3000 mb. And, please, next time try to use the bug tracker for such stuff. Thanks for your feedback. - Mar 04 2011
If your cpu is 64 bits you should install libsysactivit in /usr/lib64/ using the cmake parameter -DCMAKE_INSTALL_PREFIX
Sentinella is not who loads the needed libraries so the libsyactivity installation must be in the correct place.
The last problem you report may be caused by two versions of sentinella installed at the same time. Probably you are running the old one, please check it at the about dialog.
If you still found problems please file a bug at https://sourceforge.net/tracker/?group_id=277778&atid=1179456 adding the commands your are running to install both packages and the running desktop version. - Jul 05 2010
