Citrix session is broken

Hi!

I have problem by working with SAP System over Citrix session.

If I work with SAP System I get the error

SAPSID: connection to partner broken

WSAECONNRESET: Connection reset by peer

If I try to log on to system immediately after this error I get following error:

time out while pending for route competition

Can some one help by solving this problem?

Thank you very much

regards
