Sorry for my poor English.
I tried to use LSMCD for the object cache.
But it something wrong that after 30 mins Connection Test will be failed.

Here is the step list what I did.
1. Use CyberPanel then install OpenLiteSpeed for webpage server.
2. While install OpenLiteSpeed , also install Memcached Extension and Redis Extension .
3. According to some webpages, I should stop Memcached Extension first that prevent some problems.

Code: 
systemctl stop memcached.service
systemctl disable memcached.service
※My distributions is CentOS8

Then follow the install steps with "Compiling/Installing LSMCD"
  1. Code: 
    yum groupinstall "Development Tools"
yum install autoconf automake zlib-devel openssl-devel expat-devel pcre-devel libmemcached-devel cyrus-sasl*
  2. Code: 
    git clone https://github.com/litespeedtech/lsmcd.git
  3. Code: 
    cd lsmcd
./fixtimestamp.sh
./configure CFLAGS=" -O3" CXXFLAGS=" -O3"
make
  4. Code: 
    sudo make install
  5. vi /usr/local/lsmcd/conf/node.conf

then input

It should be list some services(?), but right now it just only
Code: 
telnet: connect to address 127.0.0.1: Connection timed out
messages.​
9.
Code: 
/usr/local/lsmcd/bin/lsmcd -v
Code: 
lsmcd server 1.4.24

That's all.

Did I missed something?
Actually, at the beginning it worked! But after 30 mins, the Connection Test become failed and load pages be very heavy.
I'd like to use OpenLiteSpeed (or LiteSpeed)+LiteSpeed Cache+LSMCD(For Object Cache )
Could someone help me to solve this problem?
