Downstream we had to resort to this:

[~gnodet], why was the {{close(true)}} removed from

Confirmed. I conducted a patch release: [1] where I omitted the above commit,
and updated the Gerrit upgrade to consume it: [2] and all Gerrit tests are
passing again.

Thanks for the code pointers. In fact, we do restrict the concurrent session
number per user, see [1]:
{code:java}
final int maxConnectionsPerUser = cfg.getInt("sshd", "maxConnectionsPerUser",
64);
if (0 < maxConnectionsPerUser) {
getProperties().put(MAX_CONCURRENT_SESSIONS,
String.valueOf(maxConnectionsPerUser));
}
{code}
However, we have not touched this are of the code recently. In fact the above
restriction was added 8 years ago in this CL: [1].
Can it be that there is a regression in SSHD session management code in 2.5.0
release?

Has the behavior of session closing changed?
When I log server-side session creation (in
{{Nio2Acceptor.AcceptCompletionHandler.onCompleted()}}) and unmapping (in
{{Nio2Service.unmapSession()}}) and the run
{{org.apache.sshd.common.forward.ApacheServerJschClientTest}}, I do see all
server sessions being closed, but most of them only after the last test. Thus
if you do more than 64 (sequential) tests, it's possible that the session map
in {{Nio2Service}} contains 64 or more old sessions. If those are still in the
map when {{AbstractServerSession#getActiveSessionCountForUser()}} is called
they'll count against the limit.
If I set
{{server.getProperties().put(ServerFactoryManager.MAX_CONCURRENT_SESSIONS,
4);}} in {{ApacheServerJschClientTest.startServer()}}, the last two tests fail
with that same error message: "com.jcraft.jsch.JSchException:
SSH_MSG_DISCONNECT: 12 Too many concurrent connections (4) - max. allowed: 4".
It's not related to JSch being used for the client – I can provoke the same
kind of failure also with the {{ApacheServerApacheClientTest}} if I set
MAX_CONCURRENT_SESSIONS to 4.

Very simple [reproducer in the JGit
tests|https://git.eclipse.org/r/c/jgit/jgit/+/165814/1/org.eclipse.jgit.ssh.apache.test/tst/org/eclipse/jgit/transport/sshd/ApacheSshTest.java]:
sets the server's MAX_CONCURRENT_SESSIONS to 2, clones and then fetches twice:
each is 1 ssh server session; the third one (i.e., the second explicit fetch)
fails.
Looks like the server does not close its server-side session when a client
disconnects.

Look for some code that involves
{{ServerFactoryManager#MAX_CONCURRENT_SESSIONS}} and
{{PropertyResolverUtils#updateProperty}}
{code:java}
/**
* Key used to retrieve the value of the maximum concurrent open session
count per username. If not set, then
* unlimited
*/
String MAX_CONCURRENT_SESSIONS = "max-concurrent-sessions";
{code}
By default we place no limit so it seems that somewhere in your code there is
one. If you wish to debug - simply look at
{{ServerUserAuthService#handleAuthenticationSuccess}} and
{{AbstractServerSession#getActiveSessionCountForUser}}
