Issue/Introduction
Error Message :
No errors
Patch level detected:Dollar Universe 6.1.00
Product Version: Dollar.Universe 6.1.0
Description :When restarting a node, the CDJ uses a lot of cpu for a long time and shows inaccurate status of job runs on univiewer console.
The file u_fmsb60 of the concerned are is quite big and there are lots of lines containing this string: "SSSSSSS99999999999999"
In order to measure the startup time of the CDJ, you can compare this two lines:
On my case, with a u_fmsb60.dta file of 100MB, it takes 6 minutes 30 seconds to sync:

Cause
Cause type:
Defect
Root Cause: The issue was due to the fact that the SBSESS records (lines containing SSSSSSS99999999999999) on the u_fmsb60.dta file were not purged correctly in particular circumstances.

Environment
OS: All
Resolution
In order to fix the issue, you first need to upgrade the impacted node to 6.7.41 and then purge manually the u_fmsb60.dta via the tool uxpursbsess.
Procedure to use it on Unix / Linux on the area EXP:
1. Stop the node: unistop
2. Backup the target u_fmsb60.dta ( cp $UNI_DIR_DATA/exp/u_fmsb60.dta $UNI_DIR_DATA/exp/u_fmsb60.bak)
3. Simulate the purge of the SBSESS orphan records to see if the issue is present on the target area:
uxpursbsess exp simulate any
4. If the issue is present ( the value of sbsess deleted is different than 0 ), then launch it without the parameter simulate so that the purge is performed:
uxpursbsess exp any
5. Launch an offline reorg so that the file size is shrunk: unireorg
6. Start again the node: unistart
7. You can check the size of the file before and after, the difference should be quite important.
Fix Status: Released

Component: Application.Server
