nchan_store_init_worker: Assertion `procslot_found == 1' failed

System Information:

- Ubuntu 16.04.4 LTS (GNU/Linux 4.4.0-194-generic x86_64)
- Nginx version: nginx/1.18.0

Initially, the Nginx was with a passenger server for Ruby on Rails support but later on the RoR get a separate droplet and from the initial server removed the passenger server.

Now I am getting an error continually like the one below

[alert] 2136#2136: worker process 19673 exited on signal 6 (core dumped)

[alert] 2136#2136: shared memory zone “memstore” was locked by 19673 ter process /usr/sbin/nginx -g daemon on; master_process on;: /build/nginx-1.18.0/debian/modules/nchan/src/store/memory/memstore.c:708: nchan_store_init_worker: Assertion `procslot_found == 1’ failed.

but here on GitHub link I have found a discussion about that like dpkg -l | grep nchan but getting nothing even the root & user’s account getting nothing, and since last more than a month getting Nginx server down again & again, over google I have fond nothing can help me out that.

Now, it’s my only headache because thousands of visitors everyday & getting a bad reputation due to the issue.

Can anyone help me out with that, please?
