From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003 Description of problem: After an up2date upgrade, client programs were not able to connect to the mysql-server. This happened on two machines (both running RedHat Linux 7.2) at the same time. After manually killing all mysql processes (the /etc/init.d/mysqld script could not stop them, because /var/run/mysqld/mysqld.pid was non-existant) mysqld could be started again, and is functioning now (20 minutes later). Version-Release number of selected component (if applicable): 3.23.54a-3.72 How reproducible: Didn't try Additional info: Before restarting mysqld, the 'top' command did not function, but returned a 'floating point exception'. The 'ps' command did function, so I could verify that mysqld was indeed running. When mysql is running again, 'top' also works.
Ok... tested this. I shut down the mysqld service, did an up2date on my 7.2 machine, restarted the mysqld service and all ran fine. My mysql clients were able to connect and extract data from the database. There was no problem with top either.
