Environment:Attachments:( 0) backtrace_1439.txt
Description:See attached [^backtrace_1439.txt], but it appears the unsolicited_mwi container is NULL when attempting to send the initial notifies. Just a guess, but it appears the container gets freed, then NULLed during unload, however it's still trying to send the notifies so c.

The unsolicited_mwi container might need to be turned into a global container.

Backtrace is from 13.  Issue is unconfirmed in 16+ which might prevent it through more aggressive module reference counting enforcing a better unload order.
