Hello, We have responded to this issue in the ticket as well. GemFire version 9.7.x, first of all, is no longer fully supported. That said, version GemFire 9.7.x is compatible with RHEL x86_64. We do not support RHEL however. We support GemFire. If recent issues exist in the latest RHEL kernel versions, please reach out to Red Hat Support. Any updates made by Red Hat should/must not break compatibility with earlier versions of RHEL 7.
