I'm running Informix enterprise replication inside Kubernetes from past 3 months and haven't faced any problem earlier. But recently I faced one issue where the Informix server was in the running state but unable fetch any record. Then I killed the container and restarted it, and then issue is resolved but I'm unable to find the root cause. Please find the error below.

Note: I'm using Gluster cluster PVC and both Informix containers which are running in the same namespace. Could anyone help me to resolve this issue?

I'm using OpenShift 3.9 and RHEL 7 is the base image used for Informix. I haven't done any changes in Informix image recently. (Informix version 12.10.FC8ADE)
