Using the PHP SDK here and I am getting a lot of events being repeated up to about 20 times leading to used a lot of my resources!
I had a look at the code my side and theres nothing that would suggest multiple triggers for the same error.
I get lots of:
vendor/sentry/sentry/lib/Raven/ErrorHandler.php in handleError at line 115
vendor/sentry/sentry/lib/Raven/Breadcrumbs/ErrorHandler.php in handleError at line 34
vendor/sentry/sentry/lib/Raven/ErrorHandler.php in handleError at line 115
vendor/sentry/sentry/lib/Raven/Breadcrumbs/ErrorHandler.php in handleError at line 34
vendor/sentry/sentry/lib/Raven/ErrorHandler.php in handleError at line 115
In the stack trace if that helps to pinpoint the issue.
