re: machine freezes with 0.9.4 and question ??

[Paul Lantinga <prl@xxxxxx>]

Hello all.  First post to lvs - I hope it's worthwhile. 

This is really a bit of a response to a previous post, hence the re: in the subject.  The original poster stated that using ipvsadm -lc would hang his ipvs server.  I've experienced the exact same thing.   Some digging through the archives and bug fix lists didn't show me anything that appeared related.   Do any of the authors have any comments on this?  It's rather hard to troubleshoot as the server locks up tight immediately - nothing in any of the logs, nothing on the console, ack.

This only happens on the development code.  v8.x has been for us, completely uncrashable. 

Lastly, great work folks!  I look forward to seeing the v9.x tree turn into stable production code.

thanks,
-Paul LANtinga
