[kamailio/kamailio] "dns_hash_put(): unlinked item" downgrade of the WARN messages to INFO (Issue #4287)
hubgurujr created an issue (kamailio/kamailio#4287)
Seeing a lot of warning messages in logs, running version: kamailio 5.8.4 (x86_64/linux) 1e6738, but I think this is false positive and should be informational, not a warning.
Jun 10 14:14:17 siprouter1-pve186 /usr/local/sbin/kamailio[8111]:WARNING: <core> [core/dns_cache.c:170]: dns_hash_put(): unlinked item 0x7fa0f9b9fcc0 Jun 10 14:14:19 siprouter1-pve186 /usr/local/sbin/kamailio[8122]:WARNING: <core> [core/dns_cache.c:185]: dns_hash_put_shm_unsafe():unlinked item 0x7fa0f9b9fcc0
This is occurring when a DNS URL changes IP but I see no processing issues with SIP Messages.

Probably makes sense to switch to INFO, but I would like to get more about the source of printing the warnings, so I pushed a commit (d79bc9b9b85f247d8b4bca37d2f84d4dcb412730) to get the file name and line. Can you test with it and paste here the printed logs in such cases?

I can’t get that commit applied, git commit/git cherry-pick is not seeing that commit hash. Can you walk me through applying that commit?
Thanks.

When you cloned the git repo, have you done it only for the branch 5.8 (ie., with `-b`)? Or for all branches?
miconda left a comment (kamailio/kamailio#4287)
You can also get only the patch/diff of the commit:
- https://github.com/kamailio/kamailio/commit/d79bc9b9b85f247d8b4bca37d2f84d4d...
And apply it with with `patch -p1 < ....`.
hubgurujr left a comment (kamailio/kamailio#4287)
OK, I’ve got the patches applied, waiting on some good log messages and will send over.
Thanks

Can you apply two more patches, test again and give again the logs?
- https://github.com/kamailio/kamailio/commit/7f349a69cb9dbc2f18ecc0ae22ec2133... - https://github.com/kamailio/kamailio/commit/81e9c4f965dcedccdc73f88c6b8f0c2f...
The `debug` has to e `2` to get the INFO from the second patch, or, if you need to keep it lower, then change in the second patch the `LM_INFO` to `LM_WARN`.
I want to track it a bit further, because, as it is, it might lead to memory leak.

Can you apply two more patches, test again and give again the logs?
* https://github.com/kamailio/kamailio/commit/7f349a69cb9dbc2f18ecc0ae22ec2133... * https://github.com/kamailio/kamailio/commit/81e9c4f965dcedccdc73f88c6b8f0c2f...
The debug has to e 2 to get the INFO from the second patch, or, if you need to keep it lower, then change in the second patch the LM_INFO to LM_WARN.
I want to track it a bit further, because, as it is, it might lead to memory leak.

Thanks for the testing and feedback! I pushed the commit to switch the warning to info, as well as to destroy the item immediately on remove. They are in git master branch, considered for backporting. I am closing this one.
