First of all welcome to HUB for your participation here. I could see you had posted this question 3 days back for the reported error log message and requesting us to provide the cause of these messages.
Looking at the below log messages:
02/24/2017 11:34:27.76 Slot-1: Denied packet on ingress interface vlanIf=1000010 slot=1 port=49, too many ACL's & packet rate is too high.
As far as my understanding is concerned this is reflected in the log if the "refresh policy" command is invoked by adding few more entries in the policy file, then after unconfiguring that specific ACL, EXOS switch will start logging messages like "Denied packet on ingress interface vlanIf=1000223 slot=1 port=1, too many ACL's & packet rate is too high ".
I can see you had already mentioned that no ACL is configured at this moment. That is true but we never know if in the recent past something was configured and later it was unconfigured. While doing this if the policy files contain more than 1 entries then later it would throw these messages.
Hope you understand whatever i have explained here referring to the provided log message and its cause.
