New issue 179: Crashes and error pages when kallithea is under load?
https://bitbucket.org/conservancy/kallithea/issues/179/crashes-and-error-pages-when-kallithea-is
zwarmapapa:
I keep getting crashes, error pages and error report mails when I'm doing several things at once with kallithea, like for example git push 2 projects each with 80+ files changed, or refresh a lot of pages in the browser.
I use SQLite, which is probably the problem? I'm using SQLite because it makes it easier to make full backups.
The webpages just show error 500 internal server error when this happens, then it sends me one or several mails. Here are two of those mails:

Just to make it clear: I normally don't get these errors, this only happens when I put kallithea under load.
When one of these errors happen, kallithea keeps throwing these errors for about 5 minutes on every action I do, then everything works fine again.
Any idea what causes this and how it can be fixed?
PS: using kallithea commit 8bc8366 (Fri Nov 27 01:48:09 2015 +0100)
