You have two errors:
At first you have an ORA-01019 ("unable to allocate memory in the user side") from the database driver. Then you have a 0x80004005 (
E_FAIL
= "An undetermined error occurred") error when trying to get the database error message.
A quick search for the ORA error:
ORA-01019[
^]
After fixing the database error you should also fix the second one. You have probably a function that tries to get and show the error message. There you should catch the failure and show an appropriate message like "Unable to get error message text for [Oracle error code]".
