Description

Scenario: Poweroff of NFS mount board

Reproduced on: WRL 8.0.0.28_standard version, BSP: fsl-t4240

 

Analysis :

 

gzclose API hangs on below scenario.

 
 # gzopen a file on remote board file which is NFS mount
 # Power off the remote board
 # gzclose the file right after power off

 

Please attachment for libraries and debug files. (Please raise ticket so that I will attach complete libraries)

 

Please check the thread 1937 on core dump.

Steps to Reproduce

The NFS server is switched off whilst the client has a file open.
