[hobbit] Hobbit bbtest-net crashing
Hi Henrik
Does 4.2.2 RC? use C-ARES 1.2.1, 1.4.0 or 1.5.3? Or have you not made any changes that drastic?
We got a test server up and running 4.2 with patches and C-ARES 1.4.0, and we will see if it also crashes.
Cheers V

Below are our 5 most recent cores. And the corresponding entry in the bb-network.log file where available. (No= t all generate the entry in the log file)
It seems the problems occur in the C-ARES library which is used for hostname lookups (via DNS).
Hobbit 4.2.0 uses version 1.2.1 of C-ARES; the current version is 1.5.3. Unfortunately there's been a small change of the C-ARES API, so we cannot just drop version 1.5.3 of the library into Hobbit 4.2.0. But it would be nice to know if the problem is still there in the latest version.
If you want to try that, you can grab version 1.4.0 from http://c-ares.haxx.se/c-ares-1.4.0.tar.gz and then change Hobbit's build/Makefile.rules: The "ARESVER" setting should be "1.4.0". Then "make clean; rm -rf bbnet/c-ares/* bbnet/libcares.*; make" and copy bbnet/bbtest-net to ~hobbit/server/bin/
If you want to try out the 1.5.3 version, drop me a mail and I'll send you the patches needed for this to compile with Hobbit 4.2.0.

4.2.2 still has the 1.2.1 version of c-ares in it.
I've added the patch needed for it to compile with the current version of C-ARES (1.5.x), so if need be we can easily drop that into the code if people have problems with the old version. This is not in RC1, but in the repository.

FWIW, using the ARES resolver on out CentOS4 x86_64 systems has been a general disaster, running much slower than disabling it. -Alan
Disabling it? Are you saying we do not need to use this module? How would I go about changing my installation to not use C-ARES? Bbtest.net is crashing at least twice a day in our environment.
Any advice appreciated.

Run bbtest-net with the "--no-ares" option.

Hmmm Found the answer. Thanks Alan. And a little caveat.
"The system resolver function does not provide a mechanism for controlling timeouts of the hostname lookups, so if your DNS or NIS server is down, bbtest-net can take a very long time to run. The --dns-timeout option is effectively disabled when using this option."
Amazing what you can learn when you sit down and carefully RTFM :-)
A little worried about implementing it just yet, but we will see how it goes.
Of course, as is always the case, since I started getting somewhere with trying to resolve this, it stopped crashing. No crashes since last night - touch wood.
