Abstract

OSP-OTHER-INCORROUT NETSERVER NOT RESPONDING AND QZLSFILET IN
MTXW

Error Description

Instances occur since upgrading the IBM i to R730 where        
NetServer response takes longer than usual, and eventually      
NetServer appears to lock up and mapped drives are not          
accessible. When this happens, the QZLSFILET job is in MTXW    
status. After a period of time the problem clears and NetServer
operates normally.                                              

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

A timing window exists in the SMB2 Read and Write request      
processors where a file reference may not be released if the    
client session begins close processing while the operation is in
progress. The dangling reference can cause the session close    
processing to take a long time to complete.                    
                                                               
IBM i NetServer has been changed to ensure file references are  
released. The PTF corrects the problem.
