Ok, I do not have a good understanding of things at the kernel level so
I may need some help getting more details. I ran ktrace on the process.
Below is the tail end of the ktrace using linux_kdump to process the
ktrace file.
692 lmutil CALL linux_socketcall(0x1,0xbfbff5c4)
692 lmutil RET linux_socketcall 3
692 lmutil CALL linux_ioctl(0x3,SIOCGIFHWADDR,0xbfbff614)
692 lmutil RET linux_ioctl -1 errno 22 Invalid argument
692 lmutil CALL close(0x3)
692 lmutil RET close 0
692 lmutil CALL write(0x1,0x280ad000,0x29)
692 lmutil GIO fd 1 wrote 41 bytes
"The FLEXlm host ID of this machine is ""
"
692 lmutil RET write 41/0x29
692 lmutil CALL munmap(0x280ad000,0x2000)
692 lmutil RET munmap 0
692 lmutil CALL exit(0)
I hope this provides what you need. Let me know if you want me to send
the entire ktrace file to you off-list.

There are no such messages.
Thanks.
