We are getting lots of time_OUT in CRM7.0 system after upgrade indicating one program SAPLSENA terminating in time_OUT loops. All work processes in SM66 are getting blocked with SAPLSENA process & there is nothing running as such in dialog process. This is hitting continuous time_out loop in system.
What I can see from ST22 this is mentioned dump.
The program "SAPLSENA" has exceeded the maximum permitted runtime without
interruption and has therefore been terminated.
