Dear Maxim,
Vanilla Tomcat9: startup and shutdown fine.
Vanilla OM5
User: when the binary is unarchived, it has a local usergroup as the default
owner. Is this correct?
(binary from OpenMeetings Web site): no configuration changes except SSL
certificate input.
Startup fine
Shutdown:
netstat gives no port binding on 443 and no pid
echo $CATALINA_PID gives blank
BUT
ps aux gives tomcat pid running
Below are CLI log and OM5 / Catalina log.
If we run shutdown command again, CLI gives “Tomcat may not be running”:

Hello Hemant,
dev@ mailing list is for discussing OM/Om community development (i.e.
discussing patch, the way to solve something, etc.)
NOT for contacting OM devs to report an issue
I don't have CentOS8 so I need detailed description of
what do you mean by "Environment is CentOS 8 (using docker) and MariaDB
10.3.x"? (OM is java application, it doesn't require docker to be able to run)
So could you run "vanilla" OM5 (without any other services, proxies, 3rd
parties etc.) and check it it works for you as expected? i.e. both startup.sh
and shutdown.sh run as correct user do it's job?
If yes - add changes one by one and continue checking
If not - compare with "vanilla" Tomcat9 - what is different :)
baby steps :)

Subject: RE: OM5: Tomcat not shutting down due to OM5 method
Dear Maxim,
I am sending this to users, but we think one possibility (not confirmation) is
this error is related to OM5 code [1]. There is a method in OM5 that is
triggering memory leak while shutting down Tomcat. The most common reason is
something hanging or delaying in Web application initializations [2]. This
prevents Tomcat to properly shutdown [1, 2].
Or, is due to something else? (We are using OM5 binary from OM Web site.
There are no customization or configuration changes.)
Here is the relevant log.
The key line in the log is: “The web application [Openmeetings] appears to
have started a thread named [nioEventLoopGroup-2-1] but has failed to stop it.
This is very likely to create a memory leak.”
