We are facing the below issue with Solace connectivity in one of the prod servers (2 nodes). Its a clustered environment and the other 3 servers in this cluster are not having this issue. The external jar file has been imported using Pega import functionality and I have checked that it is present in pr_engineclasses (as mentioned that it is working on nodes of other server boxes).
I want to understand what could have caused this issue (RCA) on this particular server alone? Also, is there a possibility to make it work on this server now without restarting the server? We are on Pega 8.5.1
