I have been having an issue with Bind hanging for several months. I am currently running BIND 9.5.1-P2 on CentOS 4.4 kernel 2.6.9-42.0.3Elsmp as mail server using MailScanner, Postfix, spamassassin-clamav, openwebmail, pop-before-smtp. Binds was hanging with 9.2.4 as well so I upgraded to the current version above. It hangs at different times and intervals. The only thing I find in the messages log is the last entry for named before the hang. Does not appear to be a memory or resource issue from my review of the system. The only way to get named running is to kill the pid using kill -9 (pidid) . When named hangs smtp service fails as it needs named to run properly. I am wondering if a kernel update is order for BIND to function properly. Any suggestions to narrow down the root cause ? Regards, Jesse Cabral
