Available process memory on OSF 3.2

Available process memory on OSF 3.2

Post by Richard Tessi » Thu, 05 Sep 1996 04:00:00

        I'm looking for a way to get the amount of memory that is available
for a process. Under several other UNIX platforms (HPUX, SCO ...) we
use the available space for the data (using sbrk and ulimit) but this
concept doesn't work under OSF (since it can allocate non-contiguous
memory blocks, the result of sbrk(0) can be over ulimit(UL_GETBREAK)
even if there is no segmentation fault). Is there a way to do
something similar(or better !) that would work on OSF 3.2 ?

1. AMD running on OSF/1 (dec/alpha) version 3.2 run on OSF/1 4.0?


        I have a configuration of AMD built under OSF/1 version 3.2

running on OSF/1 version 4.0.  

        I am experiencing a large amount of NFS timeouts and retrys

to remove files between to OSF/1 (dec/alpha) systems.

        One system is running the OSF/1 3.2 OS and the other is running

4.0 OS version.  Both running the same AMD build; (AMD version

%amd -v <cr>
