DatabaseError('database disk image is malformed') when importing multiple tickers

[Byunk]

I believe this is the same bug as #1573, and it sporadically occurs but is observed quite frequently.

Simple code that reproduces your problem

data = yf.download(["JPM", "BAC", "WFC", "C"], period="10y")

That's not debug log. Run with yf.enable_debug_mode()

[Byunk]

@ValueRaider Unfortunately, it cannot be reproduce with yf.enable_debug_mode(), still be occasionally observed though. Is it related to how frequently call API so that it affected by logging?

[ValueRaider]

No, this is an internal bug. Anything unusual about your environment? E.g. cloud or multiple process instances?

[Byunk]

Probably nothing unusual. I ran with my local macOS environment, and it occurs either while it runs with few other processes are running or no process is running at the same time.

[ValueRaider]

Can you try Git branch hotfix/database-error? #1080

[Byunk]

@ValueRaider It seems to work properly now. Thank you 👍
