Problems with web OPAC

["Lisa BILLINGHAM" <l.billingham@xxxxxxxxxx>]

Dear Innopac Users Group Members
 
We have been having intermittent problems with our web OPAC connections.
 
We find that users are intermittently denied access to our catalogue, getting a message beginning:
The page cannot be displayed
 	 
The page you are looking for is currently unavailable. The Web site might be experiencing technical difficulties, or you may need to adjust your browser settings.
This occurs when the number of users logged in is well below our maximum (e.g. may be 167 in total when we have a maximum of 300 possible logins).
 
The number of users logged in for each contention group does not approach maximum either - e.g.
 
       TOTAL        300
 
       CONTENTION GROUPS
   1 > staff         43 max - 22 logged in
   2 > public       300 max - 75 logged in
   3 > systems        2 max - 0 logged in
   4 > loans         76 max - 70 logged in
 
We also use the proxy rewrite method of authentication for database access.
 
The problem does occur when login number rise and improve when the number fall but, as explained above, the numbers of users do not appear sufficient to cause this failure.
 
Sometimes using option R - Restart a terminal is sufficient to restore access, but on other occasions access has to be restored by Innovative.
 
We have reported this to Innovative, and Software Engineering is currently investigating the cause.
 
We would be grateful for any help or advice that you can offer.
 
Kind regards
