Recently I have the 3005 upgrade installed(RS6000/320). Since then I got a lot of trouble with the ethernet. The network crashes frequently(about twice a day, unable to rlogin, telnet, etc), and the only way I know to recover is rebooting. Do other users have the same problem? I'd like to hear any advices(even how to complain to IBM). Xiaojian

My 530 (64mb/2.5gb) doesn't seem to be affected... is this a hint? Inquiring minds want to know... BAD. -- Glenn R. Stone gs26@prism.gatech.edu

BAD. Add a model 530 with 16meg to the list. I post about this (or something very similar) a couple of weeks ago. I did talk with software support but they were unable to help. They did suggest having our CE check trace data from the network card (token ring in our case) but I never got around to calling. Our solution: the problem "disappeared" after the system crashed while installing 3005 updates. I restored from backups (to 3003 and the problem was gone! I'm assuming some kind of software glich which appeared. We are now at 3005 with no problems. If someone does figure it out this inquiring mind would like to know what was/is going on as well. For now...the AIX gremlins (with deamons there's gotta be gremlins, right) fixed it!

Just thought I'd add (to the confusion of all) that I've seen no such problems while upgrading _my_ 3005 systems (320 16/320s, with either thick or thin ethernet). I was coming from 3003 - I wonder if that made a difference? -- Pat Wilson Systems Manager, Project NORTHSTAR paw@northstar.dartmouth.edu

I was coming from 3003 - I wonder if that >made a difference? Why not a bit more confusion ... We have a 520 which was recently upgraded to 3005. Our rlogins seem to fine, (I don't we use telnet or ftp very often), BUT we have PCs running FTP Inc.'s PC-TCP software to NFS mount parts 520s file systems which CRASH our IBM. My co-worker is talking to FTP to figure out what the problem is, it may have something to do with symlinks. I suspect there is also something wrong on our 520 - it should NOT CRASH, and running the same thing on the PC and mounting from our Personal IRIS does not CRASH it (it generates a few NFS errors, but it still works). -- WalteR -- -- Walter R.

Another datapoint: Our 320s w/16Mb under 3005 won't accept incoming telnet sessions from our terminal servers (of all things). They will accept rlogin connections, however. -- J.

Since we upgraded to 3.1.5 this problem has gone away, now both rlogin AND telnet from terminal servers works just fine... John

I post about this (or >something very similar) a couple of weeks ago. I did talk with software We had this problem on 3003 and 3005 on our 520 w/32MB. John Kubiak of Tech Support finally figured out that it was an mbuf deficiency. To see if you have the same problem, run the command: # netstat -m The results that I got (this was before rebooting the system, which always cleared things up) was: 912/1024 mbufs in use: 479 mbufs allocated to data 77 mbufs allocated to packet headers 124 mbufs allocated to socket structures 215 mbufs allocated to protocol control blocks 2 mbufs allocated to routing table entries 13 mbufs allocated to socket names and addresses 2 mbufs allocated to interface addresses 469/469 mapped pages in use 2004 Kbytes allocated to network (99% in use) 293646 requests for memory denied The numbers of mbufs in use, mapped pages in use, Kbytes allocated to network, and requests for memory denied were the clues. To fix this, I changed the "Maximum Kbytes of real memory allowed for MBUFS" from 2000 to 4000 using SMIT ("Change/Show Operating System Parameters"). I also had to do the following commands: # no -o thewall=4000 # chdev -l sys0 -a maxmbuf=4000 The system has been working fine since then, but it would always work for a couple of weeks after rebooting, and it's only been a couple of days. If you want to call Tech Support, the problem # is 5859. -- =========================================================================== Frank Irwin | "The game was nothing to write home about, Vmark Software, Inc. | Unless you were writing home for money." ..uunet!merk!uvmark!irwin | - Jesse Grant (thnx Mike)

Hmm... thats interesting; one of the folks here at Fermilab was sent a patched ethernet driver that is supposed to fix a "receiver hang" for the same sort of symptoms. (although his was haning roughly once every two days). The patch is labeled: APAR#: a16808 SOFTWARE LEVEL(S): ...[install instructions deleted] DATE: 06/17/91 We've installed it on his machine that was having the trouble, and one or two others, and so far no repeats. The mbuf problem sounds like a possibility too, though... ------- Marc Mengel mengel@fnal.fnal.gov
