We have experienced serious problems using x.25 and COMIO interface with
heavy x.25 traffic (over 600000 packets a day). When there are more that 30
SVC per port, and a lot of new CALL packets x25_receive fails with x25errno
267, errno 2 or 22. (x25syserror, enoent). SVC remains open until CLEAR from
the network is received (timeout). Using x25mon we can we multiple CALL
packets appearing at the port, but none is confirmed with a CF CALL.
x25_ctrl_wait signals that there is a packet, but testing the listen id, or
trying to receive it fails!
Is there a solution to the problem. We are currently developing a new server
using NPI, but the problem still remains until we manage to develop it (and
it is not easy!).


Thanks,
Ivan
