DDBv5 migration Worklow error [Compact partition failed - Failed to compact partition in MA.....Output [sh: pstack: command not found ]. ExitCode [1]:enable garbage collection failed]

HI Community,

Today we did a migration of our DDB to DDBv5 ( a grid with 4 MAs).

But we got this error message for one MA in the grid:

“Compact partition failed - Failed to compact partition in MA [MA name]. Command [sidb2 -compactfile secondary -i 68 -split 2 -cn “MA name” -in "Instance001"]. Output [sh: pstack: command not found ]. ExitCode [1]:enable garbage collection failed”

and also this error on the Workflow job “Attempts” tab:

Sourced file: inline evaluation of: `` if(v_05e48dac_fcb3_428d_801e_d8cb46c39b54!=0) { string failureReason = v_c26 . . . '' : Typed variable declaration : Class: string not found in namespace
Source: calypso, Process: Workflow

After the failed message the One MA got restored and DDB reconstructed.

Did anyone came accross this error or any suggestion to solve this issue please ?

Thanks
