Adrci very slow and causing ORA-04036: PGA memory used by the instance exceeds PGA_AGGREGATE_LIMIT

Hello,

When I run adrci command to look for last 30 mins of errors on one of my three instances it takes few minutes to get response. Sometinmes I am getting even ORA-04036 Error.

Example of very slow command: adrci> show alert -p "MESSAGE_TEXT like '%ORA-%' and ORIGINATING_TIMESTAMP >systimestamp -1/24" -term

All other adrci command are very fast eg. show problem, show incident, show home on remining two instances adrci is very fast.

I even shrank alert.log file but it did not help. Any idea what could be the problem?

Howdy, Stranger!
