Hmm, perhaps there is some way to reproduce a error?

I don't know how fast verbose logging will eat disk space, perhaps
you can check that? :-) Maybe logger could be configured to do not
log date, hostname and component, that would decrease size of logs
vastly. If not, less verbose logging could be used, let say
debug=0x00375fff, that will miss some information, but maybe would be
enough to figure out where the bug is.
