Dear Sir,
We are running SAP S/4HANA SP 9 Multitenant DB. Running on Kernel 742 DP 217 DBSL 217.
Since a couple days ago we are having the following error during the backup execution using DB13:
SQL Message: Connection failed (RTE:[89006] System call 'send' failed, rc=32:Broken pipe)
We found the SAP notes:

We did the following checks:
Check I:

Testing a Database Connection Defined in DBCON:
Could not open connection <SID> .
sql error 10.709- occured:
Connection failed (RTE:[89006] System call 'send' failed, rc=32:Broken pipe)

DATA FILE : /home/<sidadm>/.hdb/<pas_hostname>/SSFS_HDB.DAT
