Hi all,

We're running Lightstreamer Server on Linux. In the LS.sh file there are the following commands:

ulimit -Hn unlimited
ulimit -Sn unlimited

We're having trouble getting these commands to run correctly. We can set the lower limit, but not the higher limit - we keep getting an 'Operation not permitted' error. We suspect it's a Linux issue, but I was wondering if you've come across this before and know how to resolve it?

As a separate question, why does Lightstreamer need to modify the limit settings? What are the consequences of not changing these?
