SYMPTOM
Password protected subscription (zip file) generated by Intelligence Server installed in CentOS7 can not be unzipped in Strategy 10.4.

The issue happens with below conditions:
CAUSE
The issue is a derivative issue caused by KB307517, because the libz.so.1 file bundled in Strategy lib path has been deleted or renamed according to workaround in KB307517.
Thus libz.so.1 in OS lib path is used instead by zip process embedded in Intelligence Server.
Therefore the zip file can’t be unzipped properly.
ACTION:
The issue in KB307517 has been solved in Strategy 10.6 or above. Please upgrade to take the advantage.
WORKAROUND
If upgrade is not an option, recover the libz.so.1 in Strategy lib path, restart Intelligence Server and check the message in console.
If warning message like below is output, however Intelligence Server can be started and run successfully, this message can be ignored.
/sbin/sysctl: /usr/local/mstr/install/lib/libz.so.1: no version information available (required by /lib64/libdw.so.1)
