Hi folks,

when re-starting one of our containers, go-replace exits with a SEGV:

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x38 pc=0x5d2068]

At the moment, I don't have the exact command being run - nevertheless, let me know if you need more information to resolve this.

Thank you very much for your time!

Best,
