Error description
ibmproxy is down by SIGSEGV. Caching Proxy on AIX crashes at midnight when the Midnight directive is set to archive.so.
Local fix
disable archive.so fully by commenting out the following line in their /etc/ibmproxy.conf: #Midnight /usr/lib/archive.so:begin
Problem summary
**************************************************************** * USERS AFFECTED: Users of IBM Caching Proxy versions * * 8.5.5.12, * * 9.0.0.4, and 9.0.0.5 on AIX * **************************************************************** * PROBLEM DESCRIPTION: Caching Proxy crashes at midnight on * * AIX * * during log rotation. * **************************************************************** * RECOMMENDATION: * **************************************************************** 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
