Hi, I have updated the NXLOG installation to version 2.10.2150 hoping that it will fix my issue. I have NXlogs installed on 6 servers and they are work fine except one server. Thi sis afile server so there are no application installed on it. On this server I get the following errors. When I manually restart the NXLOG service everything runs fine for few days and then NXLOG stops reporting logs. I appreciate assistance in trying to resolve this issue.

I think the event source disappears while NXLog is running which is usually caused by the application being removed.
The NXLog Enterprise Edition should handle this situation better. In addition it supports the TolerateQueryErrors option which could further help.
