Looking for suggestions on what to try next. I am building a new mail server, using the DPT3332UW, and 64MB RAM, and a superMicro dual P6 board, although only running 2.2.5-beta at the time. I am getting consistent reproducible crashes in the DPT subsystem, that a parallel maching running adaptec's isn't seeing in the same way. I have 4 IBM 4GB disks in it. 2 of them configured as RAID-0, 2 of them as RAID-1. (Using dptmgr/fw0). FreeBSD is installed, and seems to run fine under light load. I'm using INETLOAD from MS, to simulate hundreds of users hitting it with mail, and another box running inetload to simulate hundreds of simultaneous POP readers. Invariably, after 20-30 hours of getting hammered, the box dies with "DPT: Undocumented error", and drops into DDB. If I take out DDB, I get a kazillion messages about stale transactions that aren't really dead, and a bunch of other errors. I have also tried a similar set up on a Digital ZX6000, with 7 Seagate Barracuda's in it, and see a similar problem. Completely different motherboard/cabling/chassis, etc. So I guess the question is. How do I help figure out what exactly is killing the DPT controller, and is development of the 2.2.x driver still on? Or is it something I just need to dump, and wait for 3.x to be solid and stable enough to use?
