Hi Dave,
The crash occours only when you associate a host to that v3 user as below:
trapsess -v 3 -l authNoPriv -u u4 xx.xx.xx.xx:162
If I do not associate the user to a host , then everything works fine.
Thanks & Regards,
Kapil.

One comment - you are mixing two styles of access control here.
*Either* use the access/group/view lines.
*or* (preferably) use "rouser u4"
You don't need both in the same file.

I've tried this with the current 5.4.x code, and can't reproduce the problem.
The noAuth command works fine, and both authPriv commands give
"Unsupported security level"
Adding a privacy token to the createUser directive makes the corresponding
authPriv request succeed (and the other one times out). But in no case does
the agent crash
We've just issued a release-candidate version of 5.4.3.
Can you try with that and see if the problem still recurs.
Dave
