*** [SQLITE_BUSY] The database file is locked (database is locked)

I am still using the plain old lxcisa0.informatik.tu-muenchen.de for 
certain tasks

Recently, a problem emerged:

$ isabelle build -b Pure
*** [SQLITE_BUSY] The database file is locked (database is locked)

I am using rev c8d92d4ced73 and a minimal ~/.isabelle/etc/settings:

init_components 
"${ISABELLE_COMPONENTS_BASE:-$USER_HOME/.isabelle/contrib}" 
"$ISABELLE_HOME/Admin/components/main"

What is going wrong here? Maybe NFS makes problems.

Thanks for any hint,
	Florian
