Hi Neus,
how are you deploying your app? Most likely solution to this is to increase size of your app server heap space. Any specifics about your development environment would be helpful if provided.
Thanks

Hi I know that this post is old, but i happened the same it and I was apache tomcat in windows and the solutions was modify the size of the memory pool of JAVA, maximim memory pool and the tread stack size in 512, 1024 and 128 only for my apps..
Hola me pasaba lo mismo y estaba usando un servidor apache tomcat, solo le cambié la memoria de la máquina virtual y me funcionó, ejemplo para mi aplicación en el administrador del apache solo modifiqué los parámetros Initial memory pool en 512, maximun memory pool en 1024 y thread stck size en 128 y adios el error,
espero y sirva mi aporte para otros, chao Saludos
Increasing the heap space sometimes only delays the problem.. you should try to search for traces of memory leak too.
Are you handling large data sets in JSON objects maybe?
