To workaround the “ thread was aborting” error try this change on the web.config file:
requestLengthDiskThreshold="88192" executionTimeout="108000" shutdownTimeout="108000" />
The two last values (executiontimeout="108000" shutdowntimeout="108000">) are the key change. The other values does not matter (regarding this problem), you can keep your current values.
Thanks,
