> Today I found the PHX engine portal in running very slow. Looking at the system, engine.log is full of stack traces with "java.lang.OutOfMemoryError: GC overhead limit exceeded" error.
> Memory on the system:
> {{# free -m}}
> {{              total        used        free      shared  buff/cache   available}}
> {{Mem:           7810        3752         475         165        3582        3576}}
> {{Swap:          4095        1097        2998}}
