Servet,

These messages are caused by a software defect in your IOS. It is not causing any incorrect operation but it does access memory in an ineffective way (multiple accesses to RAM in order to read or write a single value that could otherwise have been handled in a single memory access). The only way of solving this issue is to change to a different IOS version where this ineffectivity has been corrected by IOS software engineers.

You are running 15.1(2)GC2 which is itself based on 15.1T IOS train. This train is considered a development train where potential bugs or issues may arise with greater probability. I suggest either looking for an updated GC revision if any is available, or if possible, moving away to a stable release, either 15.0M or 15.2M.

Best regards,

Peter
