Old bug back or something is tampering HS?

I'm getting a few dozens of same WARN on a SRV running an up to date debian & Tor to publish a Hidden Service: 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux.

WARN sample (/var/log/tor/log.2):

Dec 15 04:53:19.000 [warn] rend_service_introduce(): Bug: Internal error: Got an INTRODUCE2 cell on an intro circ (for service "……….") with no corresponding rend_intro_point_t.

The Hidden Service seems working fine, any suggestion about how to investigate about it?

That's a duplicate of #8864 (moved) but on a more recent version (0.2.5). Priority set back to "normal". There might be a bug in the code that does not clean up something but the HS service is still working fine.

Can you change the log level to "debug" and attach that here to the ticket? Basically, once you see the [warn] rend_service_introduce(): Bug: Internal..., capture the log file and you can put back to normal debug your HS service. (make sure to scrub your HS service name if you don't want it there).

ASN, done.

Waiting for some more logs.

Weird bug:

• yesterday happened hundreds of time but related to 5 specific moments of the day

• today happened a few dozens of time but in the same 2 minutes.

Replying to oneday: In addition to debug logging, I suggest LogTimeGranularity 1 and LogMessageDomains 1.

No news. It's weird to see no more any entry of this after two long session, with no causality but with a regular and continuous iteration.

I noticed a lot of tor log entries with this error message when running tor 0.2.5.8-rc.

Here is the log grepping for those lines: http://paste.debian.net/142106/
