gpssh uses pxexpect version 2.1. In software only deployments of HAWQ/GPDB pexpect is not able to properly buffer information from the pseudo tty interface used by SSH
This issue is being tracked in an internal bug reference MPP-25682. GPDB upgrades prior to version 3.3 in 126.96.36.199 and this will also be fixed in the next release of HAWQ.
