I run this command,

redis-cli -p 13000 FLUSHALL

and the error was gone.

but not sure what it does, because I ran this one and nothing happened,

redis-cli -p 11311 flushall

I am facing same error when update to V12.1.7

did you run that command?, I am guessing that 13000 is the process ID (but I am just guessing)

Hi,

I was also facing the same issue.

I successfully updated to ver 12.1.7 by using below process.

Below are the Steps

  1. Taken backup of my all sites and downloaded it locally.
  2. Deleted all sites.
  3. Created new site.
  4. And updated using bench command.
  5. Restored all backup on newly created sites.
  6. Migrated all sites.
    Issues get resolved by doing above mentioned steps.

For safer side I re updated all sites.

And done successful.

Checked first on which ports redis is listening:

ps aux | grep redis
redis      426  0.0  0.2  44116  6004 ?        Ssl   2019  58:28 /usr/bin/redis-server 127.0.0.1:6379       
erpuser     1137  0.0  0.8  93272 18272 ?        Sl    2019  51:15 /usr/bin/redis-server 127.0.0.1:11311                                 
erpuser     1138  0.0  0.1  40024  3020 ?        Sl    2019  40:37 /usr/bin/redis-server 127.0.0.1:12311    

Then redis-cli -p 11311 FLUSHALL worked for me.
