ContentMergeTask-0.log shows an "Xdelta Error: 5" and "Win32 Error: Win32Error (5): Access is denied." for the related .dat.diff file. The logs may show a couple of other content merge failed errors as well, which result in 0 KB delta or getting created in TEMPCACHE folder.

SEPM 14 (any version)


This issue is typically caused by low resource (memory, disk space, CPU) conditions. For example, the SEPM may only have 4% of its available 8 GB RAM or very low disk space available when this issue occurs.


While you may find that rebooting the SEPM reduces its RAM usage to 50% or less of the total amount of RAM and temporarily resolves the issue, it will be necessary to ensure sufficient disk space is available, as well as to increase (by 1 GB increments, until the issue no longer occurs) the amount of RAM on a permanent basis. If you doubled the amount of RAM and the issue continues to occur, by way of test also double the amount of CPU cores available to the system. If the issue continues to persist in spite of the increase in system resources, please contact Symantec for further support.
