## SYMPTOMS

The failure CSLIM=8A1E is reported on LAN Manager 2.2 systems; CSLIM=8A0E on LAN Manager 2.2b systems. Serious network problems may be observed at the time of failure, including frame misalignments, corrupt packets and excessively high network utilization. Multiple traps across multiple servers may occur simultaneously, since all servers receive the same corrupt packets.

## CAUSE

The network protocol driver receives a truncated DLC administrative frame (RR) because an adapter or bridge malfunctions under network stress and generates a truncated packet that contains a valid cyclical redundancy check (CRC) but incomplete NetBEUI data.

## RESOLUTION

NETBEUI.OS2 and NETBEUI.EXE for MS-DOS have been fixed so that truncated frames are now rejected even if they pass a CRC check by the network adapter driver. However, the network device responsible for creating the truncated packets must be repaired to assure proper network performance.

## STATUS

Microsoft has confirmed this to be a problem in OS/2 LAN Manager versions 2.2 and 2.2b. A fix has been created and is included in: CSD00.089. Contact Microsoft Product Support Services for information on its availability.
