Re: pgAdmin 4 crash on startup - Mailing list pgadmin-support

Hi Sandeep, After the successful startup of pgAdmin 4 with the debugger attached, I connected to my servers and tested some other functionality without any issues. Since doing that, starting pgAdmin 4 without the debugger is also starting ok. The text rendering still isn't great, but it doesn't crash, and appears to be functioning as would be expected. This makes me suspect that either there is some configuration information that has now been saved that is preventing the problem from occurring again or that the problem only happens if some uninitialised memory is accessed, and that previously I was unlucky to have it cause problems but now am avoiding hitting bad values for that memory.
