Hello,
First of all, I want to say that I've been using StackExchange.Redis package for a couple of years without any problems. However, recently, I started experiencing strange memory leaks. Usually, I always used prepared LUA scripts (via LuaScript.Prepare), but after some point I had to introduce some manually generated LUA scripts. The new code I'm using looks like this:

var builder = new StringBuilder("redis.call('HMSET',");
builder.Append(...); 
// build some script here and then run it as string:
_connectionMultiplexer.GetDatabase().ScriptEvaluate(builder.ToString());

After several days of running, the server memory goes above 1GB (usually it stayed around 200MB). I dumped the process a couple of times and result is the same: there are many strings (500000+) with reference count = 1 in a Hashtable bucket. I'm not sure why it's there and why it cannot be freed (the script is not prepared, so it shouldn't be cached, etc).

I have attached a couple of screenshots (from MemoScope 0.9.999).

Is there any way to fix/avoid such behavior?

PS. If you need more information please let me know.
PPS. I'm using the latest version of the NuGet package (1.2.1).

Total string count:

This is how strings look like (builder.ToString() output):

Here is the reference map for each string:
