Hi all,
I am currently implementing stunnels on an Ubuntu 18.04 container running Magento 2 connecting to AWS Elasiticache (Redis) with the following configuration:
Master:
fips = no setuid = nobody setgid = nogroup pid = /home/agent/pids/redis-master.pid debug = 1 delay = yes [redis-cli] client = yes accept = 127.0.0.1:8000 connect = master.awsurl:6379
and the exact same config for the read replica with different "connect" and "accept" values of course.
Everything works great except that the container host becomes unresponsive after a few days. Doing a screenshot of the console shows that the host is out of memory and mentions stunnel4 in the same error message. Upon further digging, I found that running the tunnels progressively eats away at RAM over time. Look at the logs when setting debug to 7 shows the following suspect error message:
Possible memory leak at ../crypto/asn1/asn1_lib.c:295: 28363 allocations
Does anyone have any thoughts on this? Is it a usage/configurations issue or did I discover a memory leak here? If it is in fact a memory leak, does running a later version fix this? Is there a recommended version that I should try to run that's known to work well with Ubuntu 18.04?
Thanks a lot in advance for any help on this issue!
Regards,
Jeremy
