Does anyone know what could be causing these cracks?
Running a GX drivetrain (I believe this is an SX chain). The sprocket and cassette are 6 months old and this is the second chain this has happened to. Shifting has been reliable and smooth but this keeps happening. Going to try a GX chain next.

Fatigue. Replace it NOW!!!
what are you cleaning it with?
also, where are you buying them? counterfeit chains are more common than you’d think.
Common cause shifting while climbing and / or under heavy load,
Can happen if chain is wrong length or badly maintained or poor quality manufacturer.
Get a good quality chain and check the length against the group-set install guide.
SX can wear out quicker than GX.
Counterfeit chains, market is saturated with them.
There are some people that will claim hydrogen embrittlement, but that really is an issue if you soak your chain in some degreasers for a long time.
Pedalling…..
There are visible scrape marks on the leading edge of that side plate. What’s it rubbing on? My chains don’t look like that even after months of use.
Looks kinda like it’s constantly wearing against a front derailleur or something.
