In one of our previous articles here, we had written about eAccelerator and metioned that it should significantly reduce the server load while increasing its speed from 1 to 10 times. But during the evaluation of eAccelerator under 1000+ http req/sec. conditions, we have noticed that Apache repeatedly launches child processes untill it reaches the MaxClients server limit and causes abnormal load averages to bring multi-core and multi-cpu performance servers on their knees just in seconds. When we debug the issue, we have noticed that all complaints in gdb backtraces were somehow about nothing but Zend.

Hi everyone
This article will be about an error I receive in Excel 2010 software. Actually the same error also affects Outlook 2010. Briefly it is a hyperlink problem and when I click a hyperlink in Excel 2010 (which opens a word document in the same folder), it gives the error message “This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator” (Figure 1). The interesting part is; I receive the error when a domain group policy is applied to the logon user. If I disable the policy, error disappears and everything is fine. The same is valid for hyperlinks in Outlook 2010 emails.
