workprocess Running ENQ SAPLSENA
which means that the workprocess has sent enqueue request to ENQ server, but there is no response from ENQ server yet.
I suppose that you are using ASCS standalone enqueue server.
the possible causes are:
1, ENQ server problem
=> if so, you should find some errors from dev_enq* trace file
2, network issues which block communication between DI and ENQ server
=> you can ask you network admin to troubleshooting it when issue is happening again
3, are you enable ERS server ? it could be synchronize problem between ENQ server and ERS server
=> you can just try to disable ERS server and check again
Since this issue happens once in every month, does this issue occur on the same period every time ?
what did you perform during that period every month ?
Probably the special actions which performed every month cause this issue(see possible reasons above).
Thanks and best regards,
