The Servoy Log is the following : ```auto INFO | jvm 8 | 2013/07/29 12:16:59 | lug 29, 2013 12:16:58 PM org.apache.catalina.core.StandardWrapperValve invoke INFO | jvm 8 | 2013/07/29 12:16:59 | SEVERE: Servlet.service() for servlet servoy_webclient threw exception INFO | jvm 8 | 2013/07/29 12:16:59 | java.lang.StackOverflowError INFO | jvm 8 | 2013/07/29 12:16:59 | at com.servoy.j2db.persistence.AbstractBase.getProperty(AbstractBase.java:195) ... ...

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 ---

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)? ---

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
