### Description

We have some Kamailio servers running as an outboundproxy. Requests go to different domains. Over the time, there is a slow but steady shared memory increase. We don't see the behavior on our Kamailio servers serving as endpoint proxies using the same code.

I did a memory dump, and on two systems I inspected, I saw the same result: A really high memory usage for the `dns_cache_mk_rd_entry` function. <!-- Explain what you did, what you expected to happen, and what actually happened. -->

### Troubleshooting

#### Reproduction

When we restart our Kamailio, it starts off with just a few megabytes of shared mem used. After running for a month or two, this has increased to some hundred megabytes used. <!-- If the issue can be reproduced, describe how it can be done. -->

#### Debugging Data

This is the output of the shm dump:
