Problem after going to ML4 on 5.1

[Breslau]

I'm seeing the following error using a 3rd party file transfer program:

RPC: Unable to send; errno = Broken pipe

i can do a rpcinfo on the server side to the client (which had ml4 applied on it) and get a response back showing the desired port open on the client. another host, at ml3 does not show the same error and is able to connect to the particular server. i can also make my ml3 host a server and get the same error when the ml4 host tries to contact it.

my ml3 host will show a more detailed error:

RPC: 1832-006 Unable to send; errno = There is no proce
ss to read data written to a pipe.

i tried to look up this error code but did not find anything usefull, anyone have an idea?

thanks!

ok, i gave in and called ibm about this problem, i also sniffed the lan interface on the host with the problem and saw that the app was accepting an rpc request from another host but was then receiving a fin/ack immediately after that.

ibm suggested we update libc to 5.1.0.54, which corrected the issue. apparently the move to ml4 made rpc unhappy. i had also updated tcp.client to 55.
