• The actual used memory is >= 70% of the specified maximum. The actually used memory can be found on the main page of the Admin page, under System Information, like: Heap memory: allocated=549184K, used=371473K, max=699072K
• When there is plenty of free real memory available on the OS level, Servers in general just run faster when not memory constraint. (When 2Gb free real memory availeble just asign 2Gb, it will stays unused otherwise. The JVM will not take more memory then assigned ever)
• When the expected client load will exceed the maximum: As a rule of thumb:
  • Smart Client: assume a memory usage of about 600kb for each Smart Client. NOTE: When the Servoy HTTP Tunnel is used, assume 900kb per Client.
  • All other type of Clients (Web, Headless, Batch): the required memory for each client depends on the size and design of the solution, but should be in the order of magnitude of a couple of Mb per Client.

At all times try to keep the Server log free from javascript application errors/excpetions, all application exceptions point to possible problems inside the application!

Out of memory errors means the heap size is configured to small.
Nullpointer errors indicate Servoy codebase problems, incase these are noticed file a support case containing the log entry.
Network error are only listed as non critical (orange) which may point to (possible) networks (config) problems, when many errors are continuous listed these should definitely be investigated.
