RFC Connections Lost!

Hi ,

We got strange problem in our XI dev server, suddenly we lost RFC connections and it seems to be Java stacK is corrupted! ST22 showing Error in RFC connection.

It happend due to FLUSH CACHE(I am not understand)..but because cache refresh its happened.

Through sxi_cache i made delta and full cache ...is this cause for loose RFC connections?

and i made some multimaps ...!when i run multimaps internally java classes generated ..does java classes cause for over loading the server for corrupt server?

and when I am see using SMICM ..in toolbar Administration showing some wrong !

its like :under Administration

ICM

J2EE SERVER

? ?

it is showing question marks after J2EE SERVER ..do u have any idea why it is showing like this?

Thanks,

Regards

Uma..
