Error when displaying Active Sessions - 500 Internal server error

126 Views

Hi all,

recently I am getting errors when I want to look up the logged on users in our MII 12.0.2 system. The error displayed is

500 - Internal server error

Application error occurred during request processing

Details: java.util.ConcurrentModificationException: null

Exception id: [0002556FD9C4003400000076000EA16A00045CFF57783831]

Netweaver Log only displays the same error.

Has anyone experienced this kind of error before? All other MII portal items work as usual, it is only "Active sessions" that brings up this error, I would say, 80% of the time I call it.

This error occurs after a GoLive with more users and more traffic on the machine. Could it be some kind of memory problem? Reboot of the system does not help.

Michael
