It might be wise to do some housecleaning on your workstation, this is what Microsoft says:
Error Message:
Not enough storage is available to complete this operation.
User Action:
Do one of the following, then retry the operation: (1) reduce the number of running programs; (2) remove unwanted files from the disk the paging file is on and restart the system; (3) check the paging file disk for an I/O error; or (4) install additional memory in your system.
And yes, it does make sense if you report, that it doesn't always happen ...
cheers
