Problems: can't accept over a certain number of rcmd requests - SCO

I have tuned the system with MAXUP = 1000 , MAX_PROC = 0 but when accepting a few rcmd requests (around 70) the system wasn't accepting any more connections and I had to restart the machine. When I looked into the syslog I found "inetd[340]: accept: (for shell) Out of stream resources" netstat -m shows the following total configured streams memory: 2000.00KB streams memory in use: 304.87KB maximum streams memory used: 451.08KB I have now changed the stune so the streams memory has increased to 4000.00KB. Should it solve this problem? Thanks for any comment, Chacrint...

    Default Problems: can't accept over a certain number of rcmd requests

    I have tuned the system with MAXUP = 1000 , MAX_PROC = 0
    but when accepting a few rcmd requests (around 70) the system wasn't
    accepting any more connections and I had to restart the machine. When
    I looked into the syslog I found "inetd[340]: accept: (for shell) Out
    of stream resources"

    netstat -m shows the following

    total configured streams memory: 2000.00KB
    streams memory in use: 304.87KB
    maximum streams memory used: 451.08KB

    I have now changed the stune so the streams memory has increased to
    4000.00KB. Should it solve this problem?

    Thanks for any comment,

    Not if the `netstat -m` output you've shown is from a system that's
    already having the problem. It shows less than 1/4 of the STREAMS
    memory in use; doubling it won't help. Did the rest of the output show
    any failures?

    What release of OpenServer? What NIC (exact model) and driver (name and
    version) are you using?

    It isn't the right error message, but I wonder if you are running out of
    sockets. Run `scoadmin network`, click on "SCO TCP/IP" below the NIC
    driver, then select "Protocol -> View protocol configuration" from the
    menu. If "TCP connections" is set to 256, incrase it to 512 or 1024.

    Otherwise I would think maybe it's a NIC driver problem.

    Also look at `netstat -am`, do you see any failures in the TCP section
    at the bottom?

    Sorry, that's after I reboot. When it was having a problem I just had
    to press "reset".
     

    SCO OSR5.04 using
    NIC: DLINK 530
    Driver: HW RealTek RTL8139 Fast Ethernet PCI Adapter
     

    It's already 1024

    I reboot the machine so I do not have the output of the "netstat -am"
    when there was a problem. I will repost if I have one but I wish I can
    solve this problem before it happens again.

    Thanks for any help,

    Don't waste any more time. Get a supported network card and watch
    your problems disappear.

    "Supported" isn't really the issue. There are drivers that have never
    been through our testing, yet work fine. But if reports on this
    newsgroup are to be believed, the RTL8139 driver is a poor choice, and
    the likely cause of the problem...
