Preventive Service Planning
Abstract
These recommendations are based upon your system already having installed the most current Cumulative PTF Package, HIPER PTF Group, and Database PTF Group.
Content
The IBM i Global Support Center recommends installing the group and individual fixes listed below for corrective service and preventative maintenance. If a problem persists after the recommended fixes have been installed, the Rochester Support Center can more efficiently diagnose the problem and additional fixes may be recommended.

| 03/18/2020 | SI70523 | 5770SS1 | C9311730 | IBM i OS generic named virtual devices used by Pass-thru or Telnet are reported to be unavailable when many exist. This is caused because the process that builds the list of available devices that runs after an IPL was interrupted when ENDSBS *IMMED was ran to bring the system immediately back into a restricted state. When the process that builds the list of available devices is interrupted, it will be restarted the next time device selection processing is required. (SE71485) | ||||
| 03/18/2020 | MF65457 | 5770999 | C9116730 | Unsolicited data is not being validated properly in some cases causing the session to be closed and a LIC LOG 0700 0051 to be generated. (MA47340) | ||||
| 06/01/2018 | MF64522 | 5770999 | C8242730 | Telnet Server will handle unexpected Telnet Terminal Type negotiation after Device Name Collision which caused Telnet Server exception and 2C00 1496 VLOG and the IP Interface may quit responding. (MA46802) | ||||
| 06/01/2018 | MF63799 | 5770999 | C7283730 | VTAPI virtual device application errors errors and subsequent failure may cause other sessions to be disconnected. (MA45993) | ||||
| 11/30/2017 | SI65503 | 5770SS1 | C7283730 | TRCTCPAPP *TELNET/*VTAPI enhancement to accomodate 4096 traced jobs and avoid error MCH3802 when the previous limit of 200 jobs was reached. (SE67813) | ||||
| 11/30/2017 | MF62915 | 5770999 | C7061730 | TLS Alert records attempted to be sent during underlying TCP communication outage are leaked causing temp storage growth. (MA45978) | ||||
| 05/05/2017 | MF63620 | 5770999 | C7283730 | Interaction between NETSTAT and Telnet can cause deadlock of TCP/IP Interface. An IPL is required to recover. (MA46382) | ||||
| 12/20/2016 | MF62497 | 5770999 | C7061730 | Telnet Server LIC Tasks are driving large amounts of storage to be allocated and freed. The Telnet Server used the TCP/IP Attributes for receive buffer which was increased by default in r7.2 and r7.3 IBM i OS. The Telnet Server does not need such a large receive buffer and on systems with high Telnet activity the large amount of storage management can impact overall system performance. (MA45843) | ||||
| 05/02/2016 | MF61930 | 5770999 | C6229730 | Telnet not logging SSL Connection errors in QTVTELNET joblog (MA45567) | ||||
| Telnet sessions ended by client in race condition cleaning up with session rejection like CPF8902 "device in use" is being sent may hang the Telnet server. (MA45473) IPL required to restart Telnet. VLOG symptoms are varied and highly timing dependent: VLOG 10002207 in task TNSRIOCOMPORT VLOG 07010057 in task TNSRIOCOMPORT VLOG 1F00BB10 in job QTVDEVICE |
