It seems that you are having more then 5 unknown URI params.
One thing that you can do is to recompile with an increased number of
URI_MAX_U_PARAMS.
See parser/msg_parser.h and increase the URI_MAX_U_PARAMS from 5 to 10.
#define URI_MAX_U_PARAMS 10

If you enable debug logs, you should be able to see the URI that is
causing issues.
you can temporarily increase the debug log and the restore it via fifo:
opensipsctl fifo debug 9
opensipsctl fifo debug 3
