Has anyone running 9.3.5-p1 under Solaris 10 seen this issue? 9.3.5-P1 could cause server failures more often when it receives a bulk of queries in a short period. I'd strongly recommend you to try 9.3.6rc1, which should be much better than 9.3.5-P1 and should be as stable as 9.3.5-P2. If you still have the same problem with 9.3.6rc1, please report it again. --- JINMEI, Tatuya Internet Systems Consortium, Inc.
