Re: Program running out of memory with 2GB memory?!
Please explain what Bowtie 2 is. What does it do? What resources does it use? Is it a GUI app or a CLI app?
What flavour and version of 'buntu are you running? Are you using a swap? If you are running the Unity desktop, Unity is a resource hog and you might indeed reach the limit with only 2GB of memory. This depends on the memory requirements of the Bowtie 2 app and also on how many other services and apps you are running concurrently. But at this point,m this is just a general observation so lacking proper foundation that it is almost meaningless. Cannot advise you further without far more info.
