 * As it occurs during shutdown, it’s of no consequence, but I get that it’s annoying.
   It’s probably due to a theme or plugin doing the same thing, so there is nothing
   left to send. Narrow down the cause by selectively deactivating plugins or swapping
   themes until the notice is no longer logged. Once the module is identified, take
   up the issue through that module’s dedicated support channel.
 * There are some other possible solutions on [stackoverflow](https://stackoverflow.com/questions/38693992/notice-ob-end-flush-failed-to-send-buffer-of-zlib-output-compression-1-in).
   I cannot attest to the appropriateness of any solutions presented there.
