SSIS Package fails with Runtime Interopservices Error

I have this SSIS package that used to run fine until a month ago. It started to fail with the following error code, but it ran fine after I restarted the process again. I've tried running it all day today but to avail.

The code is taking everything from excel file and pumping it to IBM DB2 table. I know the error says that there is not enough storage, but I have another another SSIS task that is 5 times its size in terms of steps, but it runs flawlessly.

Any insight into this would be much appreciated!

Error: System.Runtime.InteropServices.COMException (0x80070008): Not enough storage is available to process this command.
