At the moment, I'm just curious at the moment if anybody else has seen this
issue:
TSM 6.2.0.0 Linux client will crash if /etc/issue is larger than a 127 byte
text file. 127 bytes or less of text, the client works fine. 128 bytes or
more, and it segfaults. >127 bytes of random data copied from /dev/urandom or
nulls from /dev/zero, and the client runs fine.
This has been replicated on both 32bit and 64bit Linux systems. The Mac OS X
client on 10.5.7 worked fine. The 32bit client was an upgrade from 5.5, I'm
not sure if the 64bit was or not, but I can find out, OS X was a new install.
Tried against different server versions, though that doesn't seem to matter.
Various bits below.
I didn't see any mention of it searching the list archives, but I also didn't
spend a lot of time searching. The IBM known issues page didn't seem to list
this.
