# What do the log entries 'adb: grow_entries ..' mean?

### Question:

Why am I getting the following informational messages on starting **named** after installing BIND 9.8.1-P1 on a set of resolvers?

```
18-Nov-2011 03:35:14.872 database: info: adb: grow_entries to 1531 starting
18-Nov-2011 03:35:14.874 database: info: adb: grow_entries finished
```

### Answer:

The ADB hash table is a potential resource bottleneck, so it is being dynamically re-sized according to usage levels. The change that introduces this new behavior was released in BIND 9.8.0:

2993.    [func]        Dynamically grow adb hash tables. [RT #21186]
