Processor terminated unexpected

Hello everyone,
We have the following error for the provisioning prosess for a LDAP account:

ErrorMessages (2024-06-12 08:51:18.737) Processor (3748) terminated unexpected.

In the Synchronization Log the provisioning process is pemanently in Running state and it doesn't terminate.
If we modify or insert an LDAP account from Browse, it successfully modify or insert the account, but if the Insert event comes from OIM, the proccess goes in frozen state with the error mentioned.
We also check the process configuration parameter to see if there is some wrong config param but all the process parameters are right.
Can you help us please?
