I can see two limits configured int.h. first one is ISC_UINT32_MAX which is the effective one and forcing the cache to be max of 4 GB and the other one is ISC_UINT64_MAX which isn't used. would it cause any issue if I just replace the two values in the server.c file. so it won't give too large value whenver the max-cache-size > 4 GB _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
