Exception 108 Expired Transaction

Hi folks,

Within one of the components of the Enterprise Server, we call a flow of the Intergration Server. In most cases this flow is working correctly. However, in some cases i get the following message:

COM.activesw.adapter.devkit.AdapterException: (108) Could not invoke script “PIGENOperation”
Unable to continue transaction
details: [Tx] Expired transaction

Question1:
Could this be related to the fact that all available threads are bussy and that by consequence the transaction timed out.

Question2:
Is there an easy solution to avoid this problem?

Any help is highly appreciated!!!
