Description

Hi,

My foreman 1.4.1 system consumes all available memory 8GB and start swapping and that in turn leads to Foreman respond slowly.
I think that all the memory is consumed when an search on an puppet module is triggered on the puppet classes page.
when doing a search on an puppet module no result is shown even after up to 20 min.

Doing an strace on the process hogging all memory just shows:
  1. strace -p 20055
    Process 20055 attached - interrupt to quit
    select(10, [0 9], NULL, NULL, NULL
Below is the output from passenger-memory-stats, the private memory usage is extremely high:
