Nicolas Lalevée commented on IVY-817:
-------------------------------------
Could it be a kernel config issue or bug ? maybe somehow the cpu scheduling for
your hardware is stuck while trying to do some networking stuff...
> If DNS is playing up, Ivy takes a lot longer to sort project dependencies

> Key: IVY-817
> URL: https://issues.apache.org/jira/browse/IVY-817
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-beta-2
> Environment: Ubuntu 8.04 with messed up DNS
> Reporter: Steve Loughran
>
> I've just upgraded to Ubuntu 8.04, and for reasons I dont fully understand.
> DNS is now very patchy; long pauses before responses coming in
> running at -d level, the pauses happen after printing all the pauses,
> finishing when the Sort dependencies response comes in
> [ivy-projects] Module descriptor is processed : org.smartfrog#sf-tasks;[EMAIL
> PROTECTED]
> [ivy-projects] Module descriptor is processed :
> org.smartfrog#smartfrog;[EMAIL PROTECTED]
> //insert 30s pause here
> [ivy-projects] Sort dependencies of : org.smartfrog#sf-m32;[EMAIL PROTECTED]
> / Number of dependencies = 9
> During resolution, the delay happens after the sort
> [ivy:resolve] Module descriptor is processed : org.apache.ant#ant;1.7.0
> [ivy:resolve] Sort done for : org.apache.ant#ant-apache-regexp;1.7.0
> [ivy:resolve] Sort dependencies of : org.apache.ant#ant-apache-resolver;1.7.0
> / Number of dependencies = 3
> //here is where the delay is
> [ivy:resolve] Module descriptor is processed : org.apache.ant#ant;1.7.0
> [ivy:resolve] Sort done for : org.apache.ant#ant-apache-resolver;1.7.0
> [ivy:resolve] Sort dependencies of : org.apache.ant#ant-commons-logging;1.7.0
> / Number of dependencies = 3
> -I'm not sure why dns/rdns should be needed during a sort, unless remote
> repositories are being polled. I'm also surprised, as java caches DNS
> responses by default.
