Dear all,

Sometimes (not always) after making small changes in the SPE to my input parameters (in my case resevoir outlets and year of becoming operational. I get this error when editor reads the files for interpetation:

Traceback (most recent call last):
File "peewee.py", line 3291, in execute_sql
sqlite3.OperationalError: database is locked

"During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "swatplus_api.py", line 119, in <module>
File "actions\read_output.py", line 164, in read
File "actions\read_output.py", line 308, in setup_meta_tables
File "peewee.py", line 2011, in inner
File "peewee.py", line 2082, in execute

File "peewee.py", line 3059, in __exit__
File "peewee.py", line 192, in reraise
File "peewee.py", line 3291, in execute_sql
peewee.OperationalError: database is locked
[13792] Failed to execute script 'swatplus_api' due to unhandled exception!"

restarting my computer solves this issue teporarly, but this is quite annoying and time consuming. Does anyone have a solution?

Thanks,

Arend

For those who encounter a similar problem:

I have found out why this is happening. When running SPE whilst you have the visualise tab open in QSWAT+ this error occurs. So you must close the visualiser every time you run SPE.
