Hello all,

since last weekend the IS error log is full of the following error message:

This message reoccurs every 45 seconds and the counter (in this case: 6) increases by 1. We are using IS 4.6 SP1 with Process Monitor and Business Integrator 4.6 .
Any help is highly appreciated.

regards, Alex

Looks as if you have a problem with one of your services not handling arrays (seems to be a vector in this case) properly - has anything changed just prior to this starting? If so, track that, if not, log a call with support - you may have some damaged component - does this work perfectly on other servers? I’ve noticed that this very easily occurs where you do a substring, and the string you’re performing the operation on is not long enough.

Hello Willem,

the exception is thrown from the build-in scheduled service monitor.updateProcessDatabase. It’s a Java service so i cannot track what it is doing exactly. The problem first occured after the system (incl. DB server) has been restarted after a power outage. I think i need to issue a service request.
Thanks for your reply.
