System.Net.Sockets.SocketException thrown by sentry with virtually no information #1962
-
|
I recently set up Sentry on two different ASP.NET 6 micro-services, but while setting it up, I get the following exception spammed into Sentry about once every 5 minutes, sometimes longer and I have not been able to reproduce this outside my kubernetes cluster. I ran the same container image locally for an hour and ran the code directly from Rider, it still never produced the exception outlined below. The stack trace also does not originate from my code base not does it give any clues as to what the heck it means. I would raise a bug report but there is no way to reproduce.

I do note that the logs also say However I can't find any tasks (That run on a timer since this bug has no trigger, and is periodic) that don't get handled wrong. I could however be wrong. That said, I suspect this may be something inside Sentry that fails for some reason |

The message in the logs indicate that the exception was caught on the Hard to tell exactly without seeing your source code, but here are some pointers: https://stackoverflow.com/a/42675271/634824 This one's older, on blocking TPL waits, but same idea: https://stackoverflow.com/a/7883083/634824 |

Digging into the stack trace: It could be on anything that calls into Sentry doesn't make any direct calls to |

Also, since you said:
I would look for anything in your code that is only done for your production environment. Especially if you have any calls to It's unfortunate that there's not more of a stack trace to go on. |

Still struggling to figure it out, but I will keep hacking at it and find what's causing the issue. |

This seems like a promising fix as I have been testing it for about 30 minutes and it's silent |
