tailwatchd failed on ns1 and ns2

[nobodyk]

tailwatchd failed @ Thu May 12 01:35:05 2011. A restart was attempted automagically.
Service Check Method: [check command] tailwatchd is not running

I keep getting these e-mails from my cpanel server. I check the tailwatchd --status and everything is running fine. I got a msg saying there's some queries that haven't been run, but I ran them manually and I'm still receiving the tailwatchd failed e-mails every hour.

The title is tailwatchd failed on ns1.mydomain.com
and the other email is tailwatchd failed on ns2.mydomain.com

I'm running my nameservers on a cpanel dns cluster. When I logged in to ssh to my cpanel dns servers, tailwatchd wasn't running. Is that normal?

[cPanelTristan]

I've checked two DNS only machines to see what services it runs and tailwatchd does run on DNS only machines. Can you please check the cPanel tailwatchd log while trying to restart tailwatchd on one of the DNS only servers?

tail -fn0 /usr/local/cpanel/logs/tailwatchd_log

I can't start tailwatchd on the dns servers, it's enabled, but I can't start it.

tail -fn0 didn't work and froze my command line. I tried tail -20

Perhaps the DBD::mysql perl module hasn't been fully installed,
or perhaps the capitalisation of 'mysql' isn't right.

Same msg on both dns servers. The main cpanel server seems fine, tailwatchd is running.

Hello

install_driver(mysql) failed: Can't locate DBD/mysql.pm in @INC

This particular error message indicates a problem with MySQL. You can try reinstalling the DBD::mysql Perl module via:

# /scripts/perlinstaller --force DBD::mysql

Once that completes, you can restart Tailwatchd to determine if the issue persists:

# /scripts/restartsrv_tailwatchd

Thank you.

That worked, thanks Michael and Tristan.
