The reason this breaks is because of a type mismatch.
The following line uses fields of the timeval struct which are both 8 bytes on
Alpine 32-bit, which results in a computed value of also 8 bytes:
b09ed9a0f2/sapi/fpm/fpm/fpm_status.c (L611)
However, it is passed to a format string which expects 4 bytes
(`unsigned long` and thus the `%lu` format specifier is 4 bytes on Alpine 32-bit),
resulting in argument corruption.
Since the value is generally small, truncating to 4 bytes is sufficient to fix this.
Closes GH-17286.
