Hi!

I'll try to help you understnad this log. Please pay attention that all 
messages are marked as (Client), i.e. they were added by fbclient, not 
fbserver.

it informs you that it failed to detach

another client noticed problems - total number of such messages is equal 
to the number of active connections

Guardian notifies you, that server died.
Side note. Server runs under guardian control and this is a reason for 
drWatson not to start. Start it without guardian (as an application with 
'fbserver -a', for example) to let Watson do it's work.

Server was restarted by fbguard.

This messages are not the reason of a server crash. Server crash is a 
reason that they arrive in the log - it's just a trace of the fact, that 
a number of clients detected server death. They arrive in more or less 
random order, therefore it seems that first of them crashed the server, 
but the rest - did not. In fact random order of records in firebird.log 
about events, that took place simultaneously, hides a real reason.
Therefore don't worry about client messages, but make drWatson run.

Alex.
