Issue: During incremental replications, a system crash occurs for source Red Hat Enterprise Linux (RHEL) 6.10 workloads running Linux kernel 2.6.32-754.6.3.el6.x86_64.
Workaround: The system crash is a Red Hat known issue for RHEL 6.10 running Linux kernel version 2.6.32-754.6.3.el6.x86_64. See the following Red Hat Knowledgebase Articles:
To avoid this issue, do either of the following:
Follow the Red Hat Bug Advisory RHBA-2018:3763, which will apply Linux kernel 2.6.32-754.9.1.el6.x86_64 to the source workload.
Use Linux kernel version 2.6.32-754.3.5.el6.x86_64 or earlier on the source workload.
After the crash occurs, the blkwatch driver might cause a failure in the normal boot process on the source workload. Remove the blkwatch driver until you have resolved the Red Hat issue. See How to Disable the blkwatch Kernel Module on Source Linux Workloads (KB 7006279).
