Hi Ramin, Thanks for sharing this problem. Please point to the exact commit you are on. If you are somewhere between: 95e38b37 ("add support for systems without legacy setrlimit/getrlimit syscalls") and 8c2f6218 (setrlimit/getrlimit: fix prlimit64 syscall use for 32-bit CPUs) then I have a simple explanation for this problem, and it is already fixed by the 8c2f6218 and the following commits. Please check the 8c2f6218 commit description.

I pushed them to github now. best regards  Waldemar Ramin Moussavi wrote,
