I sure hope someone can help me. We have just recently started running 2.9BSD on our PDP 11/70 (RM03, Fujitsu Eagle, 2 TE-16 drives, 1 DH-11, 1 Emulex DH, Decwriter). Our system is crashing at least twice a day, and we don't understand why. Some random thoughts: 1. Is there any problem with running executables that were compiled under 2.8? 2. What about executables that came off the distribution tape? I ask this because I've noticed some bothersome peculiarities about source vs. object code in the distribution... A. The released C compiler was not passing the "-i" flag to the loader, and we were unable to produce separate I/D modules. Not even the C source was coded to do this! It needed to be hacked a bit. B. In trying to remake the f77 compiler, yacc bombed out on one of its operations. I re-compiled yacc, then "make f77" again, and yacc performed OK! Nothing was changed, only re-compiled. That wasn't enough, though, because the f77 make failed later on with a message from the loader about "no text" or something like that. Can anybody explain the many discrepancies between distributed source and distributes executables? Has anybody re-made f77 on a '70? How? Is there some generic problem with running executables that we have not re-compiled ourselves? What machine was 2.9 developed on? 3. We named the root file system as the pipe device, and we only have a few hundred free blocks in that system. Could that be the problem? 4. The crashes seem to happen when the CPU gets busy, e.g. when we are re-making kernels. There is usually much file system damage. I would appreciate any comments... Sorry if this note is a little disorganized, but I guess it reflects our mood these days. -- Jeff Percival ...!uwvax!uwmacc!jwp
