All of a sudden, after months of no errors, our Post Calendar 4.0.2 queries just time-out - no results, no page update to display the calendar. For example, any click on the calendar month or day or next month (>>) or event from the event list yields an hour-glass pointer for approx. 15 seconds and then no results. The same screen remains. The submit link loads the add calendar event form, however. There are ~ 1100 rows in the events table. We have two other instances of Post Calendar on the same server that are running perfectly within separate PN 0.7.5.0 instances. There are no clues in the system log as to MySql problems or anything else.

Does anyone have any advice?

Latest information: It turns out that this time-out issue goes beyond PostCalendar and is affecting the core PN Advanced Search and loading of news stories. Also, this time-out result happens using FireFox. When IE is used there is an actual http 404 page not found message reported. Is this a server issue? Memory? Disk Space? We have checked /var/log/syslog and found no clues.

Is anyone available for hire to troubleshoot? This is a production installation of PN and we have a budget for maintenance.
