Cross site state transfer - retry mechanism not working correctly

2 sites - main (2 nodes), backup (3 nodes)

Scenario:
1. take consumer site offline
2. write data into producer site
3. invoke push(backup) operation
4. write data into consumer site (such that key set overlaps with the one used in step#2)

Configuration:

• sync backup, 2pc
• Pessimistic TX, multiple operations in a single TX (e.g. 20)

Consumer site logs indicate occuring lock acquisition problems, leading to chunk not being applied. In that case, the chunk should be re-sent, however, the retry mechanism does not wait for the reply from the retry.

pruivo's note: retry mechanism can end up in an infinite loop
