  • Logging the issue so that it can be tracked and resolved. On upgrading from a working 1.1RC1 xwiki installation, the conversion process begins and can be monitored in the log files. For all but one of our xwiki databases, all worked relatively ok (120mins a bit long, but doable). The main xwiki database (our "master for all the virtual wiki's, and co-incidentally our largest database) does not finish, and crashes our. While it was running, it was observed that several documents take over 90minutes each; these documents are unique in that they have 350+ history revisions, and a large collection of objects. We can't remove them either as they're in-process project documents. The main xwiki database has clocked in at over 28 hours without completing.
