Can you use some part of the flash disk for : swap? : i.e. if (no_swap == TRUE) {bad_things_happen(); return ENOTVERYGOOD;} NO YOU CANNOT SWAP TO FLASH. It will wear the part out too quickly if you try. We've been running off of FLASH with no swap for the better part of a year and nothing bad has happened to us. We make sure, however, that we put as much RAM into these boxes as we can to avoid the low memory situations that can lead to problems.
