    hi,

    thanks for the replies.

    LWP - light weight proccess ~ thread process.

          there for it can not be avoided.

    the overall understanding was that the process is waiting for some child
    process to get finished.

    This could be a slow disk or a slow network connection, or a slow tape
    drive.

    I went for the network and found out that there is a dial up link from my
    site to the backup client site.

    thanks for the replies,

    Samier.

    Hi,

    i have an extrem slow backup process on a solaris 8 server.
    trussing it gives me multple of the following lines:

    ...
    lwp_cond_wait(0xFF08DFA0, 0xFF08DFB0, 0x00000000) (sleeping...)
    lwp_cond_wait(0xFF00FFA0, 0xFF00FFB0, 0x00000000) (sleeping...)
    ...

    man -k lwp gives me all the syscalls but i havent found the information
    what lwp does and why it seems to slow down my backup process
    can it be avoided?

    thanks in advance
    Samier.
