      Description

      I was running some integration tests on trunk and noticed that IT log (which uses LoadTestTool with 16k records) is overflowing with this:

      13/03/21 23:02:15 WARN ipc.IPCUtil: Buffer grew from 16384 to 16971
      13/03/21 23:02:15 WARN ipc.IPCUtil: Buffer grew from 16384 to 18906
      13/03/21 23:02:15 WARN ipc.IPCUtil: Buffer grew from 16384 to 18486
      13/03/21 23:02:15 WARN ipc.IPCUtil: Buffer grew from 16384 to 22896
      13/03/21 23:02:15 WARN ipc.IPCUtil: Buffer grew from 16384 to 22253
      

      So much in fact, that

      reznor-mbp:stripe sergey$ grep -a -c "Buffer grew" it.log 
      2769498
      reznor-mbp:stripe sergey$ grep -a -v "Buffer grew" it.log > it2.log
      reznor-mbp:stripe sergey$ ll it*
      -rw-r--r--  1 sergey  staff  189440541 Mar 22 11:22 it.log
      -rw-r--r--  1 sergey  staff    1114677 Mar 22 11:33 it2.log
      

      There are two questions.
      1) Should this log be TRACE level, or there at all? it happens a lot.
      2) Is this condition normal? I am assuming the log level was set to WARN for a reason
