Hi,

I'm on Zenoss 5.0.3 and redis is unable to start.
The Helath Check fail and the error is about the metrics.

Below the redis log:

I've tried to move the "dump.rdp" file into another folder, as suggested by another user, but the problem persist.

Does someone have any suggestion

Thanks

Cause of this error might be similar to a known one.

Your disk is full so when redis tries to create a db file it fails because there is no space left on the disk and it creates zero sized db file. Starting redis fails because of zero sized db file, in CentOS db file path is like this

/var/lib/redis/dump.rdb

In newer versions of redis this bug is fixed, if you use older version of redis simply removing dump.rdb will work for you. But do this ifdump.rdbfile size is zero, otherwise do not because you might lose data.
