Thanks Chris
Finnaly using mediator servlet I discover that occassionaly performance problems depends from something blocked, some "object contention"...
We solve this pushing "release" on mediator servlet....but why this happens??
no lock in db session...??
Do you have in your experience any idea??
I did'nt find anything in log, I have to see some special logs item?

BIG Problem seems that during this BLOCKING period OTM become slower...as is JAVA process absorb 100% resource....

(CU4-linux...)

Thanks in advance
