Pradeep.

Hi,

Could you check with SAP KBA   1353668 - Locks are retained due to network instabilities

Hi Gaurav,

Issue is fixed ,  scenario is we have upgraded our ECC 6.0 EHP5 to EHP7 , here we activated  below parameter in ASCS and did kernel upgrade to latest , dbsl , disp+work, dba files

enque/server/replication = TRUE

enque/server/repl/async = 1

The above parameter is changed as per suggestion with SAP .

Once above done system is fine...

Thanks,

Pradeep.
