+2. **man:read[2]/man:write[2]** Applications that perform a single `read(2)` or `write(2)` operation on a buffer of 2 GiB or larger may receive a return value that is larger than the amount of data requested. This can cause applications to behave incorrectly or report errors. The issue affects ZFS, UFS, NFS client, msdosfs, and nullfs. +
+**Workaround**: Disable the fault-handling path by setting `debug.vn_io_fault_enable=0` in [.filename]#/etc/sysctl.conf# or using man:sysctl[8]. +
