Nonstop errors

ORA-04031: unable to allocate 32 bytes of shared memory ("streams pool","unknown object","streams pool","fixed allocation callback")

I went into OEM yesterday and was going through an export just so I could use the job that estimates the export size because I wanted to set up a weekly job and during the size estimate it died with a memory error. I didnt write it down at the time. But now I noticed this error ever since this ran. Is there a way to stop this estimate job that seems to be running somehow in the background?
