Test 28 (Integration) Failure

[QingchenDang]

I encountered an issue for running pelican_twemcache in Ubuntu.
Following the instructions, I run 'cmake ..' and 'make -j' and it does not produce any errors. It seems successfully pass all the checks and build the executables.

But when I run it as following, it automatically tear down the module:
$ _bin/pelikan_twemcache ../config/twemcache.conf
load config from ../config/twemcache.conf
set up the ccommon::log module
Set up the ccommon::debug module
create logger with filename twemcache.log cap 1048576
create logger with filename twemcache.cmd cap 2097152
Tear down the ccommon::debug module
tear down the ccommon::log module
$

I re-run the the tests, and it gets struck on test 28. After showing "Start 28: integration", it never finishes running:
$ make test

I also run it on MacOS which does not have the same problem, but it failed to run the operations using Memtier_benchmark. I did not find any related issues from others. Could you help?
