Monitor Issues Monitor extension may crash when an internal SoapClient call returns an error Database locking in high load may cause event data corruption Invalid mail settings may cause the monitor daemon to crash at startup Cache Issues Page Cache may cause a segmentation fault when under heavy stress (Linux only) Data Cache shared memory storage may cause a crash when under heavy stress (Windows Only)

2 Limitations Upgrading to this version might cause some of the settings (for example GUI password) to be overwritten with default settings. This is due to some modifications to the different configuration management mechanisms, in order to enable better configuration management in the future. IBM Informix connectivity through PDO_INFORMIX is only possible if the Informix CSDK client libraries are pre-installed on the server. Zend Server does not ship these libraries, and the user is expected to install them before enabling these extensions At a glance Zend Server is a complete, enterprise-ready Web application server for running and managing PHP applications that require a high level of reliability, performance and security.
