Issue/Introduction

Download and upload is not working anymore

We are getting error "AHD05949: Unable to acquire a repository session. File not uploaded"

1) Same error after restart of SDM, new/existing repositories 

2) The knowledge document 40173 did not help this time.

https://knowledge.broadcom.com/external/article/40173/cannot-view-or-upload-attachments-in-ser.html

3) The command "pdm_configure" did not help.

4) This additional Attachment logging was enabled, but did not reveal a specific cause:
 

pdm_logstat -n rep_daemon verbose 
bop_logging rep_deamon:xxxxx ON 


 

Environment

CA Service Desk Manager (ITSM)17.x
Windows 2012
 

Cause

There was a very long filename in NX_ROOT\bopcfg\www\CATALINA_BASE\temp

We're not sure how such a long file name got created, it seemed that someone tried to upload a file like that, which resulted in rep_daemon not to respond anymore 
 

Resolution

Delete the temporary very long filename from  NX_ROOT\bopcfg\www\CATALINA_BASE\temp
