Hello,
when I use
dns_try_naptr=on
corelog=-1
debug=-1
enable_tls=yes
use_dns_cache=off
dns_cache_init=off
modparam("topoh", "mask_key", "TEAI32l)- eauiDEUIA!?()")
and run Kamailio under valgrind, Kamailio logs:
20(21) ERROR: kemix [kemix_mod.c:229]: ki_kx_get_ruri_attr(): failed to parse the R-URI
20(21) ERROR: rr [loose.c:1011]: loose_route_mode(): failed to parse Request URI
The workflow is: I start Kamailio. A UDP-client registers. Then a websocket client calls
the UDP-client. Finally the websocket client hangs up.
Valgrind does not report anything suspicious.
When I use instead
modparam("topoh", "mask_key", "TEAI32l")
for the same workflow, with the same configuration, valgrind logs:

The stacktrace with the values of the variables is available at
https://github.com/kamailio/kamailio/issues/3350 . Or at least these things seem very
similar to me.
Any idea?
I can share the OCI-image and the full configuration.
Greetings
