After installing Dynatrace OneAgent version 1.327, Control-M/Enterprise Manager processes go down and/or do not start.
The processes crash and generated hs_err_pid*.log files.

Affected processes can include GUI Server, Forecast, Self Service, and BIM.

The GUI Server wrapper outputs messages similar to the following
(seen in emguisrv.*.std.log, note "liboneagentjava.so" on the problematic frame):

# A fatal error has been detected by the Java Runtime Environment:
#
# SIGSEGV (0xb) at pc=0x00007f219706fa65, pid=2155036, tid=2155036
#
# JRE version: (17.0.13+11) (build )
# Java VM: OpenJDK 64-Bit Server VM (17.0.13+11-LTS, mixed mode, sharing, tiered, compressed oops, compressed class ptrs, g1 gc, linux-amd64)
# Problematic frame:
# C [liboneagentjava.so+0x1138a65]
