Thanks for the responses.
Perhaps you can find something in your Redis logs, maby that will tell you something on whats clogging up all the memory.
I checked the logs and there were 3 warnings:
The TCP backlog setting of 511 cannot be enforced because /proc/sys/net/core/somaxconn is set to the lower value of 128.
Overcommit_memory is set to 0! Background save may fail under low memory condition. To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctlvm.overcommit_memory=1' for this to take effect.
You have Transparent Huge Pages (THP) support enabled in your kernel. This will create latency and memory usage issues with Redis. To fix this issue run the command 'echo never > /sys/kernel/mm/transparent_hugepage/enabled' as root, and add it to your /etc/rc.local in order to retain the setting after a reboot. Redis must be restarted after THP is disabled.
I've found solutions to all those warnings and fixed them. They don't show up on the log anymore, but Redis is still crashing as soon as it start. It almost seems like it's not starting at all.
Can you send me a private message to show your forum. I want to see it!
I can send you a private message with a link to the MyBB forum, but I can't even get the NodeBB forum to show up yet
Once it's finished I'll post a link
Alternatively, use Mongo as a DB store
At this point I'm definitely considering doing this.
