Excessive logs in dmesg

[KonsKo]

Motivation

Working with the SUT server, some tests produce a lot of excessive repeatable logs.

Scope

Run whole test suite on the SUT server or particular test (for example, t_reconf.test_stress_sched_hash.TestSchedHashLiveReconf.test_reconf_on_the_fly_for_hash_sched, there are more tests BTW with the same huge logs). Currently, this particular test is failed. Look at the dmesg. There will be a lot of the same logs :

Testing

For example: t_reconf.test_stress_sched_hash.TestSchedHashLiveReconf.test_reconf_on_the_fly_for_hash_sched

Probably fixed in https://github.com/tempesta-tech/tempesta/pull/2239 , @KonsKo could you please test that the problem is gone?

Looks like the problem has gone
