When using File Content Sensor with regular exception, the sensor results to StackOverflow and PRTGProbe.exe goes down in Services and has to be strated again. An example for the regexp is: ^(?=^.*ERROR)((?!I want to exclude this).)*$
It looks like the problem does not occur with small log files. Only after a specific size. My questions are:
Is the issue known the paessler ? Is there another way to search for a pattern in log-file and exclude some lines with another pattern(s) ?
