With Kamailio 5.6.3 I add this code
```diff
-- Routing to foreign domains
function ksr_route_sipout()
+ local y = KSR.enum.enum_query()
+ KSR.err('ENUM RESULT ' .. tostring(y) .. ' :RURI ' ..
KSR.kx.get_ruri() .. '\n')
if KSR.is_myself_ruri() then return 1; end
KSR.hdr.append("P-Hint: outbound\r\n");
```
and dial +437200101011 . The code above produces the output “ENUM RESULT 1 :RURI
sip:enum-test@sip.nemox.net”.
I have the DNS-related settings:
```
dns_try_naptr=on
use_dns_cache=off
dns_cache_init=off
```
Kamailio logs during the dial-in process:

Without topoh, calling +437200101011, resolved by the enum module to
sip:enum-test@sip.nemox.net, running under valgrind with
```
dns_try_ipv6=off
dns_retr_time=2
use_dns_failover=on
dns_srv_lb=on
dns_try_naptr=on
dns_cache_flags=1
```
I get:
* 1st test case
```
dns_cache_init=off
use_dns_cache=off
```
→ CRASHES
* 2nd test case
```
dns_cache_init=off
use_dns_cache=on
```
→ CRASHES
* 3rd test case
```
dns_cache_init=on
use_dns_cache=off
```
→ NO CRASH, Kamailio receives “SIP/2.0 488 Not acceptable here” from the remote server.
(This is not a problem of Kamailio)
* 4th test case
```
dns_cache_init=on
use_dns_cache=on
```
→ NO CRASH, Kamailio receives “SIP/2.0 488 Not acceptable here” from the remote server.
(This is not a problem of Kamailio)
In each case I have performed the test twice and got consistent results.

Closing valid bugs, without fixing the real problem, results very few current reports for
real problems in the software.
This practice leads to the wrong impression, that Kamailio has no known problems, and
therefore is good software.
This is misleading and nobody has interest in having such misleading context.

@dilyanpalauzov Hey can you confirm if this only happens on LUA config or also on the
native config file?
I've tried on native config file and it seems to be operating fine for both
dns_cache_init=off/on.

New subject: [kamailio/kamailio] Crash in dns_cache.c with dns_cache_init=off (Issue #3350)
With Kamailio 5.8 it still crashes. I use in the meantime the bytecode of luajit as
KEMI.

Hmm interesting thing, indeed with LuaJIT and your `routing_logic.luajit`, kamailio
crashes, but when used with my `kamailio.lua` does not. Both LUA files have the offending
line off `KSR.enum.enum_query()` and `dns_cache_init=off`.

@dilyanpalauzov I just pushed https://github.com/kamailio/kamailio/pull/3858 for a
possible fix.
Can you confirm that you no longer see the crash, and that it functions properly?
Thanks

New subject: [kamailio/kamailio] Crash in dns_cache.c with dns_cache_init=off (Issue #3350)
Thank you very much for looking into this!
The setup I had in the past, six months ago, with 5.7, has connected me to +437200101012.
When dns_cache_init=off without this patch applied on the 5.8 branch, with the
configuration files I have, Kamailio crashes more or less immediately after it is started,
or whenever a WebSocket connection is established.
When dns_cache_init=off with this patch applied on the 5.8 branch, Kamailio crashes after
I try to call +437200101012 over WebSocket.
When dns_cache_init=on with this patch applied and I dial +437200101012 Kamailio does not
crash, but does not connect me neither, with the latter being irrelevant here.
So I think the initial problem is not solved, but your patch addreses a problem, which has
not existed at the time I reported about this crash.

@dilyanpalauzov
So in 5.7 it worked correctly? I could try to see what changed in between.
Do you have any more details of where it crashed after the patch or some trace I can look
into?
Thanks

I pushed a new update on the PR, can you maybe try it again and report back?
With your config and without the patch, indeed kamailio crashes at some point.
With the new patch, it doesn't crash at all but want to verify that I replicated it
correctly.

I meant that in the past on 5.6 branch with my configuration Kamailio has not crashed
immediately after start. Kamailio 5.8 crashes immediately after start. With your first
version of the patch Kamailio does not crash anymore immediately after start.
The problem report here is that Kamailio 5.6.3 crashed in my configuration when I try to
call an ENUM resolved number +437200101012. With your second patch applied on the 5.8
branch, the call is performed and there is no crash. Thanks!
