Hi Christian,
I wonder if there is some interface difference or something? You
should be able to find other messages associated with this
transaction: tid=0x92257580: in your logs. compare it to successful
transactions. Perhaps this failed one is from a packet received on a
particular interface? If this is the case (the interface is different
than other successful packets), perhaps see if there are ANY
successful packets sent on this interface? Perhaps you could share
some logs and/or your configuration file?
Thank you,
Darren Ankney
