[EvgeniiMekhanik]

This bug was reproduced after #2039 so it is another BUG

[EvgeniiMekhanik]

Bug with clint.c will be fixed by 3fab38a. The problem was that when we obtain client after test was killed by OOM killer, we deal with already exist DB. When we obtain client from already exist old DB, this structure is not initialized correctly. Currently we just simply remove DB, before start tempesta, later it should be fixed in other way

[krizhanovsky]

Done in #2041
