Description (partial)


"show conn count" or "show resource usage all | inc conc-" shows a disproportionately higher number of current conns on the standby compared to the active.  "show conn | inc CLS" on the standby shows lots of conns in CLSRST state.


This appears to be a race condition when short lived conns end in RST, the conn remove directive from the active to standby may arrive before the conn create directive.
