Hi,
we are facing issues with thin servers since last few months. Its happening in random times and not specific to 1 application.
We are using Rhomobile version : 5.5.0.41

Below is the error:

thin.5.log:/opt/rhoconnect/lib/ruby/gems/1.9.1/gems/redis-3.0.7/lib/redis/client.rb:222:in `rescue in io': Connection timed out (Redis::TimeoutError)

Any help would be greatly appreciated.

Full Error:

Hello,

The version 5.5 you are using is way out of date.
I suggest you to migrate to updated version, currently supported RMS version is 7.2, it is available for download at our site.
We would be happy to offer you migration, support, consulting and development services if required.
Please email me to aepifanov@tau-technologies.com if you need further details.

Hi Alex,
I agree, We are planning for upgrade. I have noted down the contact, we will be in touch with you soon.

But, any help on this issue would be really helpful.

In Redis log, following error is recorded:

26259:M 29 Jul 14:46:09.238 # Failed opening the RDB file systemdd (in server root dir /etc/cron.d) for saving: Permission denied

The same error is described in this post: redis-db.2338650.n4.nabble.com/Failed-opening-the-RDB-file-redis-in-server-root-dir-etc-cron-d-td7964.html

kiran,

I read the given link and it seems we have two different issues:
1. Quote from your link: " Your Redis instance is somehow reachable from the world, and a malicious script is connecting to it and issuing commands to:". The topic starter closed the open port in the firewall and the issue is gone.
2. Redis Timeout. We have no idea currently. Could you show both rhoconnect log and redis log at the time when the timeout error raises?

regards
Vladimir Musulainen
