<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This check should happen once the module is found, and only if the module is not suspended.
1) It's always ok to unregister a suspended module. For example cdr_manager is suspended by default config.
2) It should never be an error if the module is not registered.
Should error be -1 to allow direct use from unload_module procedures? for example cdr_mysql could use the return from ast_cdr_unregister as the return for unload_module.</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">During shutdown, Asterisk attempts to flush out any active CDRs by calling ast_cdr_engine_term. This is to try to get as much billing data recorded as possible before Asterisk shuts down/restarts and that data is lost. Unfortunately, module unloading occurs prior to calling ast_cdr_engine_term, and the CDR backend modules have already unregistered themselves. Thus, while the records are successfully flushed from the system, there are no registered backends left to handle the data.
This is technically a problem in prior versions of Asterisk as well; however, it is far less likely to occur in Asterisk 1.8/11 due to CDRs being build on an asynchronous message bus in Asterisk 12.
This patch modified ast_cdr_unregister such that if active_cdrs_by_channel has an entry, the unregistration fails. This would have the side effect of preventing CDR module unloading via the CLI on a busy system - but if you're doing that, you're already losing billing data, so that seems like a very bad idea anyway.</pre>
