With APAR PI76339, Caching Proxy changed to a different module
loading system. The new module loading system was unable to the
archive module which is used by the default Caching Proxy
configuration to perform log rotation at midnight. This results
in Caching Proxy on AIX crashing due to a segmentation fault
each day at midnight.

Problem conclusion

The archive module was updated so that it can be loaded by
Caching Proxy's new module loading system.

The fix will be included in IBM Caching Proxy fixpacks:
- 9.0.0.6
- 8.5.5.13
- 8.0.0.14

Temporary fix

There are two workarounds to resolve this issue.

1. Use the old CP module loader system (SUGGESTED)
The old module loading system can be used by setting the
following environment variable before starting Caching Proxy:

CP_USE_LOADANDINIT="true"
export CP_USE_LOADANDINIT

2. Disable the log rotation
Log rotation can be disabled by commenting out the Midnight
directive in the Caching Proxy config.

The directive should look like this (after it is commented out):
#Midnight /usr/lib/archive.so:begin
