Hello,

We have a problem in our production portal site.

This issues happens ocassionaly , when we log in to the the frontpage of the EP , put in our log details then sometime it shows the following error.

#Error: java.lang.InterruptedException.

But when u refresh or go back to the mail screen and then relogin it retruns to normalcy and all the functions work properly.

Please let us know why this error comes up when we login in to portal.

we have checked all the logs files in work directory.

Following are the error message from the default trace files

std_server_0 .out and std_dispatcher.out shows garbage values @ the end of the file.

Hello,

Try to set the following parameters:

ms/max_clients = 600

ms/max_open_requests = 2000

This values are double the default ones. If this does not help, you can also add ms/audit = 1 to try to obtain some more information from the message server if the issue occurs again.

The parameters must be set in the profile:
