I'm writing a tty-like STREAMS driver for 386 machine running SysV3.2. The user process forks(). It then opens my device, Dups the filedesc to stdin/stdout/stderr Pushes the STREAMS line discipline module "ld0" Execs() /bin/sh My problem is this: The system console starts printing out messages about "growreg() allocation failure....". The control experiment is that when I take out the "ld0" I_PUSH, the program runs fine for ever - albeit with screwed up tty settings. What I don't understand is that message allocation/ deallocation inside STREAMS isn't supposed to have anything to do with growreg(), because msgblks are gotten from preconfigured kernel memory. Also, "ld0" works fine with the tty driver. So the bottom line is, my driver works fine without "ld0", and "ld0" works fine without my driver. Anybody any ideas? Thanks in advance. prabhu -- -------------------------------------------------------------------- Prabhu Venkatesh prabhu@Convergent.COM -or- {pyramid,sri-unix,pacbell}!ctnews!prabhu
