When unbound (DNS cache) produces an error message, it's written to /var/log/ltm as a message from tmm. However, there is no indication that the message has anything to do with DNS caching. As a result of this issue, you might see errors similar to the following: -- err tmm5[14207]: tcp connect: errno 10 -- err tmm1[14244]: comm_point_tmm_recv_from failed: Software caused connection abort -- err tmm3[11846]: recvfrom failed
Some of these messages are benign, but there is no indication of that, or the associated functionality where the message was triggered. Difficulty troubleshooting the underlying issue.
-- Unbound (DNS cache) produces an error message. -- Viewing these logged messages in /var/log/ltm.
None.
Logged messages now indicate their association with DNS cache. For example: -- info tmm4[19404]: DNScache: sending query -- info tmm4[19404]: DNScache: response for example.com. A IN
