Limitation on LD_LIBRARY_PATH on Solaris box

Question

Hi All,
I am using Tuxedo v8.0 on Solaris 2.8 box. This tuxedo server guides other servers to start up after issuing "tmboot -y" command. Following error I can see if the LD_LIBRARY_PATH is too long.
<i>"CMDTUX_CAT:819: INFO: Process id=1281 Assume started (pipe)."</i>
Is there any limitation that LD_LIBRARY_PATH should not me more than some pre defined characters?
Thanks in advance.

Answer 1

As Wayne points out, there are some temporary variables of size 2048 used to
manipulate LD_LIBRARY_PATH in tmsyncproc(), the function where the problem
is occurring. A long value of LD_LIBRARY_PATH can overwrite the values in
these temporary variables. If you keep LD_LIBRARY_PATH shorter than this,
you should be fine.

Thanks for the reply.<p>
You are right. I received one core file at $APPDIR. But the strange thingis I got the core from the "tmboot" binary. Here is the back trace which I
received when LD_LIBRARY_PATH is too long. <p>

But I did not receive any error when LD_LIBRARY_PATH is not too long. <br>
Any pointers?<p>
