If anybody could tell me more about this error it will be very appreciate.
Thank for your attention.

You server was running out of memory and therefor restarted. Look into your wrapper.conf file at the bottom. There is a default setting for that

3

There is a value of 1280MB which I suppose is the default value.
Probably there was an infinite loop that brought this lack.
I don’t expect the number of clients could be the problem because there were only 10 clients connected at the moment of memory lack.
Do you think I might increase the maximum heap size (my server is 8GB ram)?

4

I’d open a case with Servoy. The StackOverFlowError you see just before the OutOfMemoryError looks like some sort of bug. I would increase your max heap size to 3000MB.

Thank you for the reply. I’ll try both things and keep the server monitored
