Using the domino service "is member of group" leads to server panic

Hi there,

i recently started using the feature to verify if a selected user is member of a specific group.
I do use the domino service " is member of group" for that and input the notes name field and a constant as group name. The service does seem to work basically but does seem to slow down the server drastically. Just now - calling the service 2 times in a row lead to a server panic and crash 3 several times.

[0ED0:0012-17A0] Thread=[0ED0:0012-17A0] [0ED0:0012-17A0] Stack base=0xBF1FFC10, Stack size = 14048 bytes [0ED0:0012-17A0] PANIC: ERROR - LockMemHandle() Shared Handle 0xE71FD23C results in a MEMHANDLE 0x271FD23C larger than allowable Max Handle Value 157951615:1

I did have to uncheck that service within the leap app to keep a stable application and server.
Anyone else approached this?

More questions:
a) Is there any equivalent javascript action to do that, where i can input a notes name and a group name and it returns true or false?
b) On the app object there is a javascript function to get the roles of the current user. It would also be a solution if i was able to get the current roles of a named user using a text or names field.
b) The service returns a boolean with true or false. That is the optimal target field type for this? the service doesn't allow a integer field but does allow a text field as target.

IMO you should open a support case for this issue

Did you ever get this resolved?
