Description (partial)

Symptom:
Kernel panic.

Conditions:
A machine running a supported CentOS/RHEL 6.x operating system, and any version
of the connector prior to 1.9.6, can experience this kernel panic. It happens
when a file in a directory being monitored by AMP is removed (unlinked) while
the kernel is simultaneously processing that file's dentry while shrinking the
dentry cache. The kernel shrinks the dentry cache periodically to free memory,
or when a logged-in administrator requests that the cache be dropped.

This problem does not affect CentOS/RHEL 7.x.
