Hi Sebastian,
I got a single DB behind a controller and I got the following error
after one day running it:
Exception in thread "RemoveIdleConnectionsThread for backend:node8"
java.lang.OutOfMemoryError: Java heap space
Exception in thread "PingResponder" java.lang.OutOfMemoryError: Java
heap space
Exception in thread "RMI TCP Connection(118)-130.149.238.135"
java.lang.OutOfMemoryError: Java heap space
Exception in thread "RMI TCP Connection(121)-130.149.238.135"
java.lang.OutOfMemoryError: Java heap space
Exception in thread "RMI TCP Connection(123)-130.149.238.135"
java.lang.OutOfMemoryError: Java heap space
Exception in thread "RMI RenewClean-[130.149.238.135:34169]"
java.lang.OutOfMemoryError: Java heap space
Do I have to increase the Heapspace? Or is there another solution?
One solution is to increase the heap space.
If you are using caches, make sure that you have limited the cache size
or that timeouts are not infinite where it applies.
Does anyone know the minimum of system requirement for running sequoia
with a singleDB-configuration
You need just enough memory to serialize the ResultSets + the basic
footprint of the controller which is few MB.
I guess that you are not using a RecoveryLog else you should also
allocate memory for the entries and potentially the embedded database if
you are using Hsqldb.
If you are using caches, then you should allocate enough space for that.
Hope this helps,
Emmanuel
