write_dataframe() does not finish

[LuchiLucs]

I'm trying to write a pandas.DataFrame into a table using the write_dataframe function but I tried waiting 10 minutes, and it does not finish.

I limited the size of the dataframe to have around 70 rows and 40 columns, the problem persists.

In the debugger, the code is stuck when calling the libray code self.executemany(sql, arrays) into write_dataframe .

How can I know what is the problem? I can read successfully another table. The table where I want to write was just created for testing purpouses.

Thanks
