redis_ip_repu FAILED: Can't use string ("OK") as an ARRAY ref
while "strict refs" in use at (eval 132) line 484, <GEN44> line 8.
<— Not sure what that means
That's strange. Looks like a redis status reply, instead of a
ref to table reply, as expected to be a result of an EVALSHA
command. Perhaps it could be a leftover from some previous failure
with redis?
Does it happen with every message of just occasionally?
Search the log at debug level for ' redis: ', see if there
was a previous error there. Which version of Redis was that?

OOM command not allowed when used memory > 'maxmemory‘.
# takes about 250 MB of redis memory per 100000 log entries
$redis_logging_queue_size_limit = 300000;
I modified redis, to have "maxmemory 536870912".
Yet I don’t know how to calculate this value.
Hopefully this warning disappears.
Check
$ redis-cli info
It will provide information on the current memory usage.
Use this to estimate a suitable limit, if you choose
to set maxmemory.
The $redis_logging_queue_size_limit just puts a cap
on a json queue size in case that noone is reading
from this queue (e.g. some monitoring/logging process).
Otherwise this queue size normally contains just
a few entries.
Besides the json log queue, the redis memory is
used also for pen-pals data and for IP reputation.
These use automatic expiration (configurable),
and the size needed for these depends very much
on your mail traffic and its diversity.
Moreover, if redis-based Bayes database backend
is configured in SpamAssassin, this needs to be
taken into account as well. See man page
for Mail::SpamAssassin::BayesStore::Redis
