Varnish 7.1.1 panic - cache/cache_wrk.c:629 #3868
Comments
Firstly, the intention behind this panic is a good one - to improve your system's uptime by restarting the varnish worker process if something goes terribly wrong. The respective parameter is thread_pool_watchdog. Other than that, this could be a bug in the watchdog code, but we have not seen anything like that for long, so at this point I would be tempted to point to "other reasons". On a related issue, the stack trace points to a potential issue in our panic handler, but that is secondary and non-causal. |
@Vormillion can you please let us know which binaries you are using? If you built varnishd yourself, please make the binary available for download somewhere. |

I appreciate if someone can help me understand what can be potential source of this issue.
