should i worry?

The error you quoted is indicative of potential drive failure. Since you haven't described your system, as requested in the Forum Rules, conveniently linked at the top of every page in red, it's hard to know if this is a significant problem.

The error you didn't quote is the one to be scared of.

4gb ddr3 1333mhz ram

4GB of RAM is insufficient memory to run TrueNAS, and is likely to result in a variety of problems over time.

If you would go into the shell and post the output of "smartctl -a /dev/ada1" then we can provide better assistance. In my signature is a link to decoding your SMART output, recommend you read it and you can diagnose the problem yourself.

And as my friend has said, 4GB of RAM is not enough, hopefully you have multiple sticks of 4GB RAM.

If you are just messing around with TrueNAS to get a feel for it, well if it runs just know that it will run at a disadvantage due to the low RAM and you will experience performance issues.

performance issues.

And some recent complaints suggest middleware crashes due to swap filling as well.
