There are various potential causes - some due to bugs, some due to genuine memory limits.

So first, capture some detailed diagnostics about the error

1) alter system set events '4030 trace name heapdump level 536870917;name errorstack level 3';
2) wait for the error to occur at least once
3) alter system set events '4030 trace name context off; name context off';

This will generate a trace file with extensive debugging information - you can then log a support call with Oracle to work through the issue.

And 11.2.0.1 is a very old, and very unpatched version.... You (a) really should be on 11.2.0.4 and (b) be looking at upgrading to a supported version!
