When building a Client Tree, we dynamically increase the Client Tree structure (array) according to records stored on a file. We are falling over for a NAT1129 – “Physical Terminal Buffer Overflow
I believe the physical terminal buffer is governed by the LS and PS parameters at startup. You could try setting them to the max in the startup (LS=250,PS=250).
With NAT425 NATOS has two new parameters TIOBSZ1 and TIOBSZ2 to maintain the size of the terminal buffer. For NWO server increase TIOBSZ2.
With NAT426 NWO automatically adapts the size of the terminal buffer. So configuration of the terminal buffer in a NWO environment is not necessary anymore.
