Memory Exception with Debugbar and Doctrine

I’m having a similar issue working with Google’s Firestore client. I believe my issue is that when an exception occurs the debug output tries to track down all loaded classes, which with a huge library like Firestore (and maybe Doctrine?) kicks it. I haven’t bothered troubleshooting it because in my case the underlying issue is some other exception triggering the trace, not a Norma toolbar load, but you might check you log files just in case. If it is loading fine on production it probably is just a case of loading too much data and there’s not much to be done for it.
