Intermittent error status 84, 83, 87 and 2074

Hi everyone,

We've been experiencing backups with our VMWare lately with intermittent status 84, 83, 87 and 2074. Started checking from the MSDP status but its always up and not going down. We've followed some workarounds namely:

• Adding the TCP Keep Alive in registry (because we also encounted status 636 before) but has been eliminated already. 
• Adding touch files DPS_PROXYDEFAULTSENDTMO, DPS_PROXYDEFAULTRECVTMO based on the technotes, and DPS_PROXYNOEXPIRE.
• Increased client timeouts
• Checked the logs and saw some errors like "connection reset by peer", "db_getClient=227"

Information:

• NBU Version (All servers): 7.6.1.2
• OS (All servers): Windows Server 2012 R2 Standard

Below is the detailed status of one of the jobs.
