[Buildbot-devel] Database is locked exceptions in 0.8.5

We are currently running buildbot 0.8.5 and have been getting occasional 
'database is locked' exceptions. These usually manifest as a trigger 
failing to start its target builder (causing the calling builder to lock 
up until we manually stop it).

I saw a note in the buildbot manual about adding serialize_access=1 to 
the sqlite DB URL, but we tend to have a lot of builders running at once 
so would prefer not to lose all concurrency if there is another possible 
fix for this. Also, before trying to add that parameter is there any 
useful information we can try to provide for a bug report?
