we are experiencing problems with three 4.11 GW servers in an OSPF environment. The POA server is generating a “OSPF sequence number mismatch” error which references the GWIA server on the same segment. When this error occurs, all GW clients in this segment lose IP connectivity for about 15 minutes, afterwhich the network returns to normal. This has happened four times since October. No noticable trends have been seen and network utilization has been well within acceptable limits.
