Sorry if I am some sort of annoying, but I am really curious in this
case. Latest SUN patch fixed following bug:
Bug ID: 6476945
Synopsis: System unable to reboot properly after proftp ftp session.
System unable to reboot after proftp ftp session. On a subsequent "init
6" the system appears to go all the way down until "uadmin 2 0" is
running then the systems controller or lom initiates a XIR. Problems
dependant on proftp version, kernel patch level.
Problem witnessed on Sf25k/Sf6900/Sf490.
The problem cannot be reproduced with Sun's ftp package. However proftp
is a widely used ftp package, and bugs descriptions found on the proftp
website actually point to Solaris OS bugs for root cause.
Problem easily reproducable. See below:
High level reproduction steps:
- Install Solaris 8
- Install kernel patch 117350-38
- Instal Ncurses library
- Install Proftpd package 1.2.9 - Conduct an ftp session
- init 6
- System will hang/crash reboot when it has almost reached OBP.
Note: If an open ftp session is running during the "init 6" a crashdump
CAN be made, otherwise it cannot!!
Crashdumps available, Solaris sustaining involved, OP N1 currently
reproducing this problem.
Find kernel patch and proftpd version that match together. (See
BUG ID 4817079 has no more info inside, but, according SUN, it was fixed
in previous patches. I was not able to find anything in proftpd
discussion beside this bug (SUN is refering to some information on

Part of the issue is that it's hard to know what is going on; many on
list (myself included) do not have Sunsolve access, so knowing what
patch numbers, from Sun, mean is difficult.
