<![CDATA["Poll Manager" hangs since 3.9.229 on server start]]>I'm running a NetXMS server at version 3.9.178 with multiple zones for our customers, one zone has a single proxy node configured. Whenever I try to update to a newer build the server service starts up but the "Poll Manager" goes to "not responding" within a few seconds. I am able to connect with the console right after the service start, if I'm fast, afterwards any new connection hangs after supplying the login credentials.

I'm not sure but I suspect it has to do with this item from the changelog:

*
* 3.9.229
*

- Fixed server deadlock related to multi-zone configuration
[...]

What is the best way to analyse this problem? I tried raising the debug level but I'm not sure what I should look for, there are many nodes configured and many connections are happening after server start.
The server runs on Windows Server 2019 with MySQL as database.

At least in my offline testing enviroment I can't reproduce any more server locks. I will update the production environment when the next official build is released.

It's in windows task manager -> details. You can share a link to it in a private message.

  • It has nothing to do with agent communication, it happens also in an isolated testing enviroment without outside communication.
  • The console login hang has nothing to do with the "Poll Manager", this happens also if the Poll Manager does not go into "not responding" state.
  • If I put all nodes to "Unmanged" everything works fine. If I enable a few nodes, for example four nodes in two different zones, following happens:
    • Sometimes, a few seconds after the server has been started it is impossible to login, this happens not every time. It hangs at "Sychronizing objects".
    • The command "show pollers" shows two "zone" pollers which seem never come to an end.
  • There is nothing helpful in the logs, even at level 9, at least to my eyes.

I tried the latest build 3.9.298 with the same results. On build 3.9.178 and older everything is working fine, this behavior started with 3.9.229.
If I can test anything or do some debugging please let me know.
