Jmeter - why linux gives different answer than windows? - redirect

Question

I wrote a test plan on Windows 7. I remotely started a test on two machines, both Windows Vista. A problem came up when I tried do same thing on Linux - I used the same test plan.
I can login a group of users and simulate their behaviour, but when I try to log them out nothing happens.
On windows, they are logout but linux gives me empty response data. Listeners show green status so I'm rather confused to what's going on. Should I change something in properties or is it problem with my script?
EDIT:
Script:
Login user using authorization data. every user gets different JSESSIONID.
Simulate user behaviour using Access Log Sampler.
Logout user.
On Windows, everything works fine login and logout. Listener shows: sample result, request data and response data for every sample.
On linux response data is blank for every sample.
Examples of Sample result for
windows and
linux
Request Data is the same for both.
Response data for linux is blank.
EDIT2:
Test Plan
setUP Thread Group
Clean cache server
Clean file with JSESSIONID
Thread Group
HTTP Request Defaults
Login (once only controller)
Acces Log Sampler
using beanshell script i save JSESSIONID (cookie variable) to file
Cookie Manager
tearDown Thread Group
HTTP Request Defaults
read JSESSIONID from file
logout all users
Cookie Manager
result tree
Summary report
Logout must be performed after all samples from access log are done. That's why i save JSESSIONID to file to share same session between thread group.
Ok somehow I eliminate error with response. Apparently there was a problem with java version on linux server.
Current problem is that when i start remotely script on Linux it doesn't follow redirect. The same script on win XP or Vista follow redirects and user is logout.
Exp.
GET connection.rpc?logout=D5D076123FD6CCBF137FE1673F531006
On Windows I get two redirections and user is logout.

It is strange because during authorization there are a few redirects and linux performs them correctly.

Answer 1

You should check that jmeter accesses correctly your jsessionid file on linux:
check path is ok (no )
check read access
If you are using distributed testing, issue may be that file is not found by agent or some file is overwritten by another agent

Answer 2

Problem is solve, yupi :)
It turned out that the target server has set the lock for some machines. On such a machine was a Linux. That is why I could not log users in a separate thread.
Therefore, if someone encounters a similar problem (from one machine request are handled correctly from another are not), he should check if his machine have correct permission in my case i needed to do correct entry in adm.list in test server.
