The log force change is the critical one, as it can happen a leaf functions in the code paths and hence greatly increase the maximum stack depth of any path that needs to unpin an object or lock a buffer. Cheers, Dave. _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
