I am running sharepoint server 2010 with 8GB RAM. I have a SP Designer Workflow running on my portal. The server used to respond but now when users try to hit the URL they get an error message. I checked on my server only to realise that the OWStimer.exe takes much memory which explains why users get request time out error. I restarted the server but after 2-4 hrs its start running very slow and memory usages goes to 95%(7.95 GB). OWSTIMER.exe takes 6.6GB.
I read many articles and they think this might be happening due to the fact that I have a workflow running but the reality is that I also need that workflow for my document approval.
Your assistance will be much appreciated.
