REQUEST_RUNNING_TOO_LONG при попытке деплоя с помощью Ant Migration Tool

I'm trying to use Ant Migration Tool for deploy all changes from one organization to another. When I run it for a large set of metadata (all possible), it running for about 8 minutes and fails with error:

[code]build.xml:35: Failed to process the request successfully.
Cause(UNKNOWN_EXCEPTION): REQUEST_RUNNING_TOO_LONG: Your request was running for too long, and has been stopped.

Total time: 8 minutes 34 seconds[/code]

I increased [b]sf.maxPoll[/b] and [b]sf.pollWaitMillis[/b] but still getting the same error.

build.xml:
