In NCDware 3.2.x Xremote, customers are seeing errors in the Xremote log file 
which look like:

SendPacket: write:: Operation would block
SendPacket: write:: Operation would block
SendPacket: write:: Interrupted system call
SendPacket: write:: Operation would block

Typically, these can be ignored as long as everything is working OK.

On HP systems, there can be a lot of these messages and the clients will hang,
so that nothing works in the Xremote session.
The root cause of the problem is that HP-UX has pretty small tty buffers and 
we're frequently overflowing.  A small change made between 3.2.BK and 3.2.CA 
seems to have exposed that.

There are two solutions. One is to start Xremote with the following command:

	xinitremote -- -pktsize 120

pktsize is an undocumented option that sets the packet size. 

Another solution is to use pre-3.2 hostside binaries.

There still may be SendPacket write errors in the log file, but the session 
should run OK.
