So what's causing the load? ps on the host and inside UML should provide some kind of clue as to what's going on. Jeff |

Jeff, You asked what caused the load, it seems that identd is one, but I assume just because it is trying to use resolve to get ip's for fqdn's. If I go init level 2, it's fine and very quick, but going to init 3 causes the slug like behavior. On the host side I assully see two of the "linux" threads running at about 50% level each, on the UML side I see what ever process like nslookup at the top, however, though UML will be very sluggish, it's top doesn't report a high load. Basically I can do anything with IP numbers, but FQDN's never get resolved. I checked the setting of resolve.conf, it's identical to the host which has 0 issues with name lookups. I'd be more than happy to let you have access to the machine if you like. doug |

I have the same problem with the redhat images (7.0/7.1/7.2). After certain services load, UML takes 100% of CPU even after the process that caused the slowness was killed. Mysqld comes to mind, and many other services as well. ----- Original Message ----- From: "Jeff Dike" <jd...@ka...> To: "Douglas Fils" <fi...@ii...> Cc: <use...@li...> Sent: Friday, January 04, 2002 1:16 AM Subject: Re: [uml-user] a call to nslookup causes very high load.. > fi...@ii... said: > > I can network ok by IP number, but any attempt to use a FQDN for a > > machine fails for debian and for redhat will cause the machine (both > > the UML mchine and the host) to obtain very high load averages and > > become extremely unresponsive to on the net, to the point I have to > > almost kill the UML from the host. > > So what's causing the load? ps on the host and inside UML should provide > some kind of clue as to what's going on. > > Jeff > > > _______________________________________________ > User-mode-linux-user mailing list > Use...@li... > https://lists.sourceforge.net/lists/listinfo/user-mode-linux-user > |
