[MSNoise] MWCS sql crash

I get a strange crash part way through my MWCS step (see below), and compute_MWCS is not finishing. E.g. I have 5 frequency bands, but for bands 2-4 only 1 of 10 station pair MWCS's get calculated, even though all the data is there in the stacks. I have tried rerunning comute_mwcs by changing the flag back to 'T' for the station pairs where mwcs did not get calculated, but it still crashes. This crash is repeatable. Any thoughts? (p.s. I also initially tried remaking the stacks, but it crashed at the same point. The data looks good in the stacks) -ashton During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/ashton/.local/lib/python3.5/site-packages/sqlalchemy/engine/base.py", line 1139, in _execute_context context) File "/home/ashton/.local/lib/python3.5/site-packages/sqlalchemy/engine/default.py", line 450, in do_execute cursor.execute(statement, parameters) File "/home/ashton/anaconda3/envs/msnoise/lib/python3.5/site-packages/pymysql/cursors.py", line 165, in execute result = self._query(query) File "/home/ashton/anaconda3/envs/msnoise/lib/python3.5/site-packages/pymysql/cursors.py", line 321, in _query conn.query(q) File "/home/ashton/anaconda3/envs/msnoise/lib/python3.5/site-packages/pymysql/connections.py", line 859, in query self._execute_command(COMMAND.COM_QUERY, sql) File "/home/ashton/anaconda3/envs/msnoise/lib/python3.5/site-packages/pymysql/connections.py", line 1096, in _execute_command self._write_bytes(packet) File "/home/ashton/anaconda3/envs/msnoise/lib/python3.5/site-packages/pymysql/connections.py", line 1048, in _write_bytes "MySQL server has gone away (%r)" % (e,)) pymysql.err.OperationalError: (2006, "MySQL server has gone away (BrokenPipeError(32, 'Broken pipe'))") The above exception was the direct cause of the following exception: -- Ashton F.
