Over the past week, some of our users have experienced an error code when opening Task Manager in Command Prompt. This problem can occur due to many factors. Let’s look at them now.

To open Task Manager, right-click the Start button on any taskbar. Select “Task Manager” from the list of products that appears and Task Manager should launch. Open a command prompt, type “taskmgr” and press Enter. Task Manager starts right away.
CPD338D “An error occurred while retrieving data”
The LAN card has expired and the main recorder has stopped. For more information about changing timeout settings, see “Service Recommended Timeout Settings for IBM, HP, and Lexmark Print Servers” earlier in this document.
This may also be due to a selective TCP/IP protocol violation that can occur when the printer is returned to the local network via a Lexmark MarkNet print server that includes Lexmark Optra printers with internal network cards. This particular protocol violation is known as a double SYN issue and is described in the following IBM Informational APAR:
IBM Informational APAR II12692, LIC-COMM-TCPIP AS/400 SENDING RST DUE TO INCORRECT SEQUENCE NUMBER
In the case of our own double SYN problem, the publisherThe printer is attempting to open a connection over which the Lexmark Optra printer sends a SYN (sync request). Due to heavy network congestion, the iSeries Multilevel does not receive a SYN ACK (sync acknowledgment) from the printer with sufficient efficiency, so it sends a hard SYN request a second time. The Lexmark MarkNet device sends two SYN ACKs, recognizing the two SYNs sent by the iSeries, but the second SYN recognized an invalid sequence number, causing the IBM System i to send a RST to the printer to reset to zero or end communication. This is required to connect to printers that write to operating system spool files rather than print.
TCP/IP connection tracing may be required to confirm that a particular double SYN issue is occurring. If this occurs, in many cases this can be resolved by contacting Lexmark for a firmware update for the Lexmark MarkNet and Lexmark MarkNet Pro Series adapters. To obtain a firmware update, please contact the Lexmark Customer Support Center at 1-888-LEXMARK (or 1-888-539-6275) to discuss and resolve your repetitive ordering issue.your SYN, or request firmware updates 191 or 192 (or higher). ). According to Lexmark Technical Support, a custom firmware update can also be easily downloaded from the following URL:
Note. The latest firmware version of the Marknet Series X2000 and MarkNet N2000 Series adapters does not have this issue. This issue can occur with older MarkNet, MarkNet XL, and MarkNet XLe connectors, but only one update can be provided because these adapters do not have enough memory for the software. If this problem occurs with these older adapters, try to reduce network congestion, replace the MarkNet adapters regularly with newer adapters with the exact firmware update, or stop using these printers with the R440 or OS later./400.
If the CPD338D was returned with return code 3426 It (rc3426), this may indicate that the print site or network card (NIC) is often not configured for two-way email. Make sure Parallel Approach is set toBiTronics, Bi-Directional or ECP/MLC, not Centronics.
Receiving a CPD338D message with return code 3426 (RC3426) most likely indicates that the printer or print server does not support PJL. In many cases, the printer or image server does not support PJL but still supports SNMP. Changing the PJL 3812 device descriptor *lan to an SNMP 3812 device descriptor *lan can solve some problems. This can usually be done by setting the user options parameter (USRDFNOPT) to *IBMSHRCNN and changing the system driver program parameter (SYSDRVPGM) from *hppjldrv *IBMSNMPDRV.
For more information, see the following configuration document:
N1019572: SNMP device description *LAN 3812
CPD337C “Session with device &1 ended abnormally”
The CPD337C message indicates that the interconnect cannot establish a socket connection, but unfortunately it can be issued for several reasons. In this case, check the following:
Usually change the system driver program from *HPPJLDRV to *IBMSNMPDRV.
Some devices configured on a physical printer have the idle timer (INACTTMR) set to *NOMAX or to a value other than *SEC15 recommended. INACTMR, commonly referred to as the release timer, indicates how long a connection to a physical printer port has been maintained after all the buffer information has been printed from the output line. Timer inactivity is determined by patterns, not seconds. A value combined with 5 means that the connection will leave the port 5 minutes after all spooled files have been printed from the final results queue. Determine all resources configured for the printer andMake sure they are all set to INACTTMR, which will be *SEC15.
A network feature called an Intrusion Prevention Engine (IPS) can detect print packets as dangerous and block the entire connection.Download this software now to fix your PC and increase its security.
