These problems kinda started out of the blue. We didn't have any updates recently, so we can't pinpoint it down to something we changed that would be causing this.
It looks like Clients are not being cleaned up properly. We see Clients keep increasing during time. (But we have no idea if this is the problem)
We use webclients and headless client as rest service. (Both stateless rest as with the itech plugin with state)
When it freezes, the Servoy Server Home isn't accessible anymore. (Other pages still are.)
What we see at the times it happens, the active connections of the repository database server is full. (We have increased it a couple of times, now it is 50/50 for example) And eventually other databaseserver connections also get exhausted.
From that point on, no new users can login.
But we have no idea what is going on at that time that it freezes.
Part of dumpstack, rest of it is in the attachment.
