Winsock error 10055 - out of buffer space, solutions ?

[Michael Pye]

Hi all,

I am quite frequently experiencing the above problem, i.e. some server
apps on the NT4, SP5 box are not able to listen for incoming
connections stating winsock error 10055, which is "no buffer space
available, an operation on a socket or pipe was not performed because
the system lacked sufficient buffer space or because a queue was
full."

I've followed some MS guidelines and set the following MS tcp/ip
parameters:
HKLM\System\CurrentControlSet\Services\TCPIP\Parameters I added:
MaxUserPort set to 0xfffe (hex), 65534 (dec)
TcpWindowSize to 0x4470 (hex), 17520 (dec)
TcpTimedWaitDelay 0x1E (hex), 30 (dec)

but this not made a significant improvement.

Is the maximum amount of open sockets purely based on available memory
? If so we can upgrade the memory but just wondering if this the case,
and if any other settings tcpip can be tweaked.

Thanks,

Try the usual steps first.

1. Increase page file size
2. Increase the registry max size (same page as page file.)
3. Reapply your SP.
4. I run the machines at SP6 since I don't have Lotus notes to deal with.
5. Contact the vendor for software updates? Who/what program?
6. I hope you didn't use the diskette that came with the NIC! Update the NIC
driver.

Thanks for that, I've increased the paging file size and that seems to
have helped.

Know of any good tech docs. that explain the use of the paging file
and recomended sizes, the NT server resource kit has next to nothing
on paging files ! Is it possible in NT to have a swap partition
instead of just a file too ?
