Lost connection to MySQL after unexpected server restart.

[fk0]

I can't get module to work after restarting DB server, just don't see messages are logged there. Module restart via web GUI does not seem to work either. Also tried ejabberdctl update and it didn't help.
I suppose start/stop module behavior is not correct.

How can I make sure it will be working after restart? Does the module track the status of DB and reconnects properly after table is checked?

Here's what erlang.log shows

fixed the issue manually by invoking:

1. ejabberdctl debug
2. emysql:remove_pool(mod_log_chat_mysql5_db).

I think this issue happens due to missing handling of hanged up pool which couldn't be re-used at the module start.
