[LDM #UYH-624598]: LVS realserver switching loses data

Indeed. If the LDM system isn't being restarted, but only the downstream LDM-s 
are 
reconnecting, then you shouldn't miss any data-products and pqact(1) won't miss 
a beat.
The log message that contained the string "{NONE, 
"SIG=e2c0f8838b2642a11c8b7943174ae825"}}"
indicates that the downstream LDM requested data-products beginning with the 
last
successfully-received data-product.

When this happens, can you verify that the data-product is not in the 
product-queue
via the pacat(1) utility?

Are you using the "-o 21599" option with pqact(1)?  It would have to be in the 
LDM
configuration-file if you were.  And if the LDM system isn't being restarted, 
then
the use of that option in the pqact(1) EXEC entries is not necessary.
