Sounds like an issue with your SSD? Can you supply a dmesg, and details on the SSD, make/model/supplier, as well as the motherboard and how the drive appears to the BIOS?

This *was* reasonable advice for the older generations of CompactFlash, but may no longer be a consideration with newer flash/SSD drives. I have run many embedded servers (mostly OpenBSD on Soekris) without swap, never had any problems traceable to the lack of swap space. >> And if you are using an application, which is writing >> a lot of things into files, put the respective dirs into >> ramdisks! > > Combined with this is even dumber. > > If you can't swap, you're already in trouble if you run into memory > pressure.

Actually, the above is standard advice for running any Unix on flash, as people have been doing with Soekris and CF since at least 2001. The idea isn't to put "the filesystem" into RAM, but rather to reduce the write operations by mounting filesystems used for frequently written smal files (e.g. /var/tmp) as ramdisks. Kevin
