Description of problem:
It appears that the log rotate is happening every 1M, which is too low for diagnosing issues. See /etc/ovirt-engine/engine-service.xml:

<subsystem xmlns="urn:jboss:domain:logging:1.1">
            <size-rotating-file-handler name="SERVER">
                <formatter>
                    <pattern-formatter pattern="%d %-5p [%c] (%t) %s%E%n"/>
                </formatter>
                <file path="/var/log/ovirt-engine/server.log"/>
                <rotate-size value="1M"/>
                <max-backup-index value="30"/>
                <append value="true"/>
            </size-rotating-file-handler>
            <size-rotating-file-handler name="ENGINE" autoflush="true">
                <level name="INFO"/>
                <formatter>
                    <pattern-formatter pattern="%d %-5p [%c] (%t) %s%E%n"/>
                </formatter>
                <file path="/var/log/ovirt-engine/engine.log"/>
                <rotate-size value="1M"/>
                <max-backup-index value="30"/>
                <append value="true"/>
            </size-rotating-file-handler>
