You can provide the tcpdump's raw dump of the session (sniffed with the -s 1500 or whatever MTU you have). This may sched some light. > My colleagues report and problems with ssh and apache on this server. Haven't seen any with SSH, but Apache tends to close keep-alived connections on the -CURRENT. Try disabling them and see if this will help. More verbose description of problems your colleagues are seeing may also help. Thank you! -- Eygene
