what JunOS version do you use? On EX3200/4200, everything above 9.3 is not recommended upto now AFAIK, and even for 9.3, the last service release (9.3S1.6) should be used in favor to the regular releases. Haven't heard any experiences yet regarding the brand new 9.3S4.1, but PSN-2009-07-461 reads as if it may help the one or other. rgds, .m
